Cement and lime production emits greenhouse gases that deplete the ozone layer, resulting in environmental problems. Consequently, people in the villages have resorted to using Cassava mortar to save money. Given the low-income level of the population, many cannot afford decent housing since costs have risen and continue to rise from 20,000ugx in early 2001 to 40,000ugx today for a bag of 50kg cement from the West Nile region and a 20kg bag of lime from 5000ugx previously to 12,000ugx currently. In real terms, the income levels are still very low and poverty levels are 41.7% of the population. However, engineers, construction managers, and relevant stakeholders have not embraced the use of cement Cassava starch mortar mix to bond the bricks because they do not know the performance of the brick wall constructed with the mortar mix of Cement Cassava Starch. Therefore, there is a need to investigate the strength of cassava starch mortar, compared to cement mortar because this will greatly reduce the cost of construction and impact positively on the environment.Item Restricted Investigating the Factors that Affect Structural Integrity of Buildings Under Construction in Kampala Region.(Kabale University, 2024) Tusingwire, MosesThe construction in Uganda contributes up 12% to the country’s Gross domestic product. It’s a vibrant sector that employs many skilled and unskilled youth in the country. The acute need for housing and other infrastructure to spike up and push forward the country’s vision of 2040 and the millennium development goals makes construction a major sector of focus. However, this in Uganda is being challenged with poor integrity of structures leading to failure and collapse of many structures. This collapse happens 6 (Six) times on average yearly prompting the need to research on what causes this loss of structural integrity. This research has through a literature review identified three elements of Material quality, workmanship quality, and methods of executing work to be assessed for being the influencing factor to structural integrity loss. Ways to enhance the integrity of structures have also been identified and stated in this report. The material was acquired through observation, sampling, and focused discussion as well as secondary information on sites about test results, and local authority checks. Data collected was analyzed using Excel to generate histograms, charts, and descriptive statistical information.Item Restricted Assessing the Effect of Groundnut Shell Ash-Lime Stabilization of Reclaimed Asphalt Pavement for Road Construction.(Kabale University, 2024) Tumusiime, InnocentPavement rehabilitation and reconstruction generate large quantities of reclaimed asphalt pavement (RAP) and recycling into new asphalt paving mixtures is the predominant application. RAP acceptance in road bases and subbases has been limited, because of the lack of laboratory and field performance data while large quantities of groundnut shell ash (GSA) are generated from the combustion of groundnut shell and also disposed in large quantities on production sites and production of Lime not only imposes financial burdens but also contributes to environmental degradation and carbon emissions. This paper presents the results of the laboratory evaluation of the characteristics of GSA-Lime stabilized RAP with a view of determining its suitability for use as highway pavement material in flexible pavement construction. An X-ray fluorescence test was conducted on GSA to determine the chemical composition. Preliminary tests (Natural moisture content, Particle size distribution, and Atterberg limit) and engineering tests (compaction and California bearing ratio (CBR)) were conducted on the RAP samples in their natural state. (GSA +Lime) was then added to the RAP at 5, 10, 15 and 20% proportions. Atterberg limits, compaction, and CBR tests were conducted for each addition of (GSA +Lime). The RAP - (GSA +Lime) mixtures were subjected to British Standard (BS Heavy) compaction effort to determine the compaction characteristics and California bearing ratio (CBR). Test results show that the properties of RAP improved with GSA-Lime treatment. RAP was classified as A-1-a using the AASHTO classification system and the general rating as sub-grade in accordance with AASHTO (1986) is excellent too good. The values of Maximum dry density (MDD) increased from 1.894 and 2.016 g/cm3 at 5% and 10% (GSA +Lime) treatment respectively and decreased furthermore with an increase in the percentage of (GSA +Lime) while the optimum moisture content (OMC) increased with increase in (GSA +Lime) content in the RAP - (GSA +Lime) mixes. The test results show that there was a decrease in the liquid limit ranging from 34.5% to 31.2% at 0% and 20% (GSA +Lime). The CBR values increased at 5% and 10% (GSA +Lime) treatment from 2.6% at 0% to 20% and 49% respectively at 95% degree of compaction and from 2.8% at 0% to 22% and 65% respectively at 98% degree of compaction and values of CBR reduced with further increase in the percentage of (GSA +Lime). Optimum stabilization was obtained at 10% (GSA +Lime) where CBR values of 49% and 65% at 95% and 98% degrees of compaction respectively. This optimum mix (GSA +Lime) is suitable for use in the construction of the G45 Subbase layer and G60 Base course layer in road construction according to Uganda MoWH&C (2005). This research provides the results of the evaluation of (GSA +Lime) stabilized RAP as highway construction material, as it is based on CBR determination. Further studies can be conducted to evaluate the effectiveness of different types of lime like quicklime.Item Restricted Assessing the Effect of Air Blast Loading on the Structural Behaviour of Reinforced Concrete Column.(Kabale University, 2024) Kasyage, AbubakaliThis project investigated the effect of air blast loading on the structural behavior of reinforced concrete (RC) columns, essential components in various infrastructures. With increasing concerns over safety from explosive threats, understanding how RC columns respond to dynamic loading is crucial for enhancing structural resilience. The study utilized advanced finite element analysis and the CONWEP method to generate pressure-time histories for different explosive scenarios, which were then applied to RC column models in Abaqus. The research focused on evaluating key parameters such as peak pressure, impulse duration, and the columns' resulting deformation and failure modes. Findings indicate that increased charge weights and reduced stand-off distances significantly elevate the risk of shear and flexural failures. The study underscores the importance of incorporating nonlinear material behavior in simulations to accurately predict structural responses. Ultimately, this research aims to provide insights and design recommendations for improving the blast resistance of RC columns, contributing to safer urban environments against potential explosive threats.Item Restricted Development of Pavement Condition Index and Roughness Index Relationship for Optimal Pavement Maintenance Strategies: A Case Study of Johnstone Road.(Kabale University, 2024) Bogere, DavidPavement maintenance is crucial for ensuring road safety, reducing congestion, and minimizing repair costs. However, determining the optimal timing and strategy for pavement maintenance remains a challenge. This study investigates the correlation between the Pavement Condition Index (PCI) and Roughness Index (RI) to develop a numerical model for describing the relationship of indices for pavement maintenance decision-making. Using statistical analysis and data visualization techniques, a significant correlation was found between PCI and RI, with a coefficient of determination (R²) value of 0.47 means that about 47% of the variation in PCI can be explained by the IRI values using this model. While this suggests that the model is capturing a significant amount of the relationship between PCI and IRI, there is still room for improvement, as about 53% of the variance in PCI is not explained by the model. The R² value is simply the square of the correlation coefficient (r) when you're dealing with a simple linear regression model. Since the PCI is a measure of road pavement conditions (on a scale typically ranging from 0 to 100), an RMSE of 7.77 means that the model's predictions for PCI are, on average, about 7 to 8 PCI units off from the actual value. The study recommends using PCI and RI data as inventory data for decision-making, prioritizing pavements with PCI values ≥50.3 and RI values ≤ 5.12 m/km for maintenance. Regular monitoring of PCI and RI values is also recommended to ensure timely maintenance and prevent costly repairs. This research benefits the Uganda National Roads Authority, Ministry of Works and Transport, and Local Government Department of Works, providing a framework for optimal pavement maintenance strategies.Item Restricted Assessing the Effects of Solid Waste Dump Sites on the Quality of Water Resources: A Case Study of Kabale Municipality Dumpsite(Kabale University, 2024) Mutaawe, Bob WamalaThe assessment of the effects of solid waste dump sites on the quality of water sources was done with the main objective of determining the possibility of contamination of the open and ground water sources by the resultant leachate from the municipal solid waste dump site at Kabalaga Hills in Kyanamira. The improper management of the leachate from the dump site accompanied with the uncontrolled access to runoff in the rainy season together with the impaired rainwater harvest system on the dump site structures makes it very vulnerable. This therefore makes the leachate easily carried away by the runoff from the rainwater and the water from the roof of the dump site structures and these get deposited in the stream of water and this is likely to the aquatic life in the stream as well as the other users such as the livestock farms in very close proximity as well as irrigation schemes. The study among other reasons was also carried out to characterize the leachate produced at the dump site, to characterize the neighboring water sources that included two gravity springs and a stream as well as identify any possible contamination and the most vulnerable to contamination of the water sources stated above. Water (collected from a radius of 1000m) and leachate samples were collected from spring one (317 meters from the dump site), spring two (608 meters from the dump site), a mainstream, River Rwabakazi (973m) as well as from the leachate collection pit present at the dump site using suitable sampling bottles. Some sample tests were done at the site while others were carried out at Mbarara National Water and Sewerage Corporation laboratory and among the tests that were done included pH, turbidity, electrical conductivity, TDS, TSS, BOD, and COD. These were compared with the WHO and Uganda standards for potable water. Conclusions and recommendations were drawn based on the results analysis that was done using charts and graphs from the resultant data that was obtained from the various site and laboratory analysis processes.Item Restricted Design and Simulation of a Sugarcane Juice Extractor.(Kabale University, 2024) Akampurira, AmonThis project involved the design of a sugarcane juice extractor machine engineered to crush sugarcane at a rate of 14-15 kg per hour, catering to the increasing demand for fresh sugarcane juice in small to medium-scale commercial settings. The primary objective is to optimize juice yield while maintaining high operational efficiency. The design features a robust roller system capable of processing sugarcane stalks of various sizes, ensuring effective extraction with minimal wastage. The use of food-grade materials that as stainless steel in all components that come into contact with the juice is a key focus, ensuring the design adheres to strict hygiene standards. The machine is designed to be compact and user-friendly, making it suitable for vendors who may have limited space and technical expertise. Although this project is focused on the design phase, it provides a detailed and comprehensive blueprint that can be further developed into a fully operational machine. The design process involved careful consideration of factors such as juice yield, energy consumption, and ease of maintenance, ensuring that the final design meets market needs.Item Restricted Assessing the Durability Behaviour of Cement Stabilized Soil Bricks in Kabale Municipality.(Kabale University, 2024) Muzahura, RonaldThe construction industry in Uganda and across Africa is undergoing a significant transformation as stakeholders seek sustainable and cost-effective building materials. Traditional fired bricks, while widely used, pose environmental challenges due to deforestation and high energy consumption during production. In response, cement-stabilized soil bricks (CSSBs) have emerged as a promising alternative, combining local materials with cement to enhance durability and structural integrity. This research project focuses on assessing the durability behavior of CSSBs specifically in Kabale Municipality, a region characterized by unique climatic and soil conditions. The results for the compressive strength of CSSBs clearly indicate that increasing cement content enhances the compressive strength of CSSBs. The substantial jump in strength from 10% to 20% cement content highlights the critical role of cement in providing structural integrity. The findings align with the UNBS standards, which specify a minimum compressive strength of 3.5 MPa for CSSBs, confirming that bricks with 10% cement and above meet and exceed this requirement. The results for water absorption show a reduction in water absorption with increasing cement content is a critical finding, as lower water absorption rates correlate with enhanced durability and resistance to moisture-related degradation. The UNBS standard allows a maximum water absorption of 15% for CSSBs, and all tested samples with cement content of 10% or more fell well below this limit. The unstabilized bricks (0% cement) demonstrated significantly lower compressive strength and no water absorption capacity, highlighting the necessity of cement stabilization for enhancing the performance of soil bricks. In conclusion, the results suggest that a cement content of 10% to 20% provides an effective balance between compressive strength and water absorption, making these percentages suitable for producing durable CSSBs in the local context.Item Restricted Design and Simulation of a Prosthetic Knee Joint for Amputees in Hilly Terrain.(Kabale University, 2024) Mabirizi, AliThis project examined the design and simulation of a prosthetic knee joint for above-knee amputees in hilly areas, Prosthetic knees are state-of-the-art medical devices that use mechanical mechanisms and components to simulate the normal biological knee function for individuals with transfemoral amputation.

The primary objective is to explore sustainable alternatives to cement in concrete production by using locally available Banana Peel Flour while ensuring that the performance of the modified concrete remains within acceptable standards. Banana Peel Flour was introduced at varying percentages (0%, 5%, 10%, and 15%) by weight as a replacement for cement in the mix. Tests were conducted to assess the slump, wet density, bleeding, and compressive strength of concrete specimens at 7, 14, and 28 days of curing. The results indicate a decrease in workability and compressive strength with increasing Banana Peel Flour content, though up to 5% replacement showed acceptable performance for non-structural applications. The study concludes that a 5% Banana Peel Flour replacement is a viable and sustainable option for reducing cement usage without significantly compromising concrete strength. This research provides valuable insights into sustainable construction practices and proposes guidelines for the partial substitution of cement with Banana Peel Flour. Recommendations are made for further studies to investigate the long-term durability of Banana Peel flour-modified concrete.Item Restricted Investigating Use of Crushed Glass as Partial Replacement of Sand to Improve Finish Mortar Strength.(Kabale University, 2024) Ashaba, DennisThe need to value wastes and the opening towards the use of sand replacement materials, both in mortars and concretes, with the purpose of promoting increased sustainability of building materials, were the grounds for this work that aims at the formulation of mortars with crushed glass aggregate. In this experimental study, the production of finish mortar using finely crushed glass and surface finish blocks using crushed coarse glass are investigated. The mechanical properties of the mortar composite of crushed glass at different percentage compositions are investigated. The test results show that the partial replacement of sand by finely crushed glass at a level of 20% by weight has a significant effect on the compressive strength of mortar as compared with the control sample because of the pozzolanic nature of the fine glass. Results indicate the pozzolanic reactivity of this waste and open possibilities for the use of this material in mortars. Mortar is a mixture of cement, sand, and water made into a thick paste that is used to bind two surfaces with each other and is used as a binding material between stones, concrete, and bricks. Mortar is typically a matrix that contains cement, lime, alkali-activated binders, fine aggregates (sand/rock powder), adequate water, and possibly superplasticizers or viscosity modifying agents added. The chemical composition of mortars indicates that they are most commonly composed of Calcium oxide and silicon dioxide. The high calcium oxide content and low magnesium oxide content probably mean that lime was provided from calcareous stones rather than dolomitic.Item Restricted Effect of Recycled Concrete Aggregates on Plain Concrete Compressive Strength and its Environmental Sensitivity.(Kabale University, 2024) Mugisha, ElaijahThis research aimed to establish the effect of recycled concrete aggregates on plain concrete compressive strength and its environmental sensitivity. It was guided by objectives that involved comparing the properties of RCAs and NCAs, to develop an optimal concrete mix design that incorporates RCAs, determining the optimal percentage ratio of RCA that maximizes compressive strength and environmental sensitivity, and finally determining the physical properties of concrete produced (fresh and hardened state). Mainly the research was about the compressive strength of plain concrete using recycled concrete aggregates. The concrete was designed to have a 25MPa compressive strength and slump range of (25-75) mm. The ratios of replacing natural aggregates with recycled concrete aggregates were 0%, 20%, 40%, 60%, and 100%. The test samples were crushed to determine their compressive strength values after 7, 14, and 28 days of curing. Other test samples were exposed to environmental factors after 28 days of curing for instance elevated temperature (1 hour, @105 ℃ ), humidity, and rainwater for 14 days and compressed to note the change in compressive strength of natural concrete and recycled concrete and results showed that recycled concrete is more affected by environment factors than natural concrete made with virgin aggregates. The results showed that slump decreases with an increase in replacement percentages and also strength reduces with an increase in replacement ratio. From the experimental results of this study, the optimal replacement percentage should be 24.7%.Item Restricted Comparison of Concrete Strength Development Using Different Brands of Cement of N32.5 in Uganda .(Kabale University, 2024) Beinamani, EdidiaThis research investigated the comparative strength development of different cement brands available in Uganda, focusing on their performance over various curing periods and associated costs. The study evaluates three widely used cement brands: Simba, Tororo, and Hima, analysing their compressive strength at 3, 7, 14, and 28 days of curing. The objective is to identify the most cost-effective cement brand that meets the required strength standards for various construction applications. The methodology involved preparing and curing concrete samples with each brand, followed by testing their compressive strength at specified intervals. The results reveal significant variations in strength development among the brands. Simba Cement demonstrated the highest compressive strength across all curing periods, making it the best choice for high-strength applications, albeit at the highest cost. On the other hand, offered a compelling balance of cost and strength, emerging as the most cost-effective option for general construction needs. Tororo and Hima Cements, while providing lower strengths, still serve specific applications where budget constraints are a factor. The findings underscore the importance of balancing cost with performance in cement selection. provides the best value for most construction projects, while Simba Cement is recommended for critical structural elements requiring maximum strength. Tororo and Hima Cement are suitable for less demanding applications. This research contributes valuable insights for stakeholders in the Ugandan construction industry, aiding in the selection of the most appropriate cement brand based on specific project requirements and economic considerations.Item Restricted Investigating the Partial Replacement of Crushed Run Rock with Reclaimed Asphalt Pavement in Base Course.(Kabale University, 2024) Ninyesiga, BrunoOverlay and maintenance resolve medium distress, but reconstruction may be feasible and economical while Asphalt pavement is badly deteriorated with time and traffic. This requires the removal of existing pavement surfaces. Recycling such construction waste has benefited from an economic to sustainability point of view and reduces the exploitation of natural resources. The shortage of virgin aggregate supplies along with the increase in processing and hauling costs has encouraged the use of reclaimed material from the old structure as base course construction materials, and involved in regular practice in various countries around the world. However, RAP materials may not be conventional road-making materials and need improvement. This study aimed to investigate the Engineering properties effect of using RAPs and CRR in their natural state by conducting common laboratory tests in the first phase, and Second phase of the study was intended to analyze the strength and interpret the optimum allowable percentage as partial replacement of CRR blended with 10/90, 20/80, 30/70, 40/60, 50/50 proportions by total weights for RAP as compared results with the general specification for base course materials. According to the general specification, the natural blends of RAP-CRR were classified. The mechanical and physical properties test results for neat RAP aggregate give ACV, AIV, LAA, SG, MDD, and Water absorption of 11.4%, 9.2%, 10.2%, 2.41, 2.130, and 1.62% respectively. Also the mechanical blending of 30% RAP aggregate and 70% CRR test results were 15.9%, 13.8%, 16.6%, 2.230, 2.68 and 1.24% for ACV, AIV, LAA, MDD, SG, and Water absorption values respectively with 141KN and 170KN when soaked and dry in water for TFV results. The results obtained from Gradation, Atterberg’s limits, SG and water absorption ACV, AIV, LAA, and Compaction results indicate that Mixes containing 30% RAP contents were successfully replaced CRR in the road base course layer of Asphalt concrete.
