This segment of population is mainly dependent on use of biomass consisting of firewood, charcoal, straw, crop residues to meet its energy demand for cooking and other domestic needs. The aim of this project is to provide detailed analysis of how to generate biogas energy from ordinary pit latrine. To achieve this, the existing pit latrines were first studied, and then different biogas technologies were also studied. An appropriate technology was then selected and the design equations covering the volume of the digester, inlet and outlet chambers were developed considering the shape of the digester. The final layout ofbiogas pit latrine was developed. This study was motivated due to inefficient exploitation ofbiogas from ordinary pit latrines. The developed layout ofbiogas pit latrine has been found to be appropriate for biogas production using human waste as substrate. Proper sealing of the gas storage facility is emphasized to avoid leakage and occasional maintenance is highly encouraged.Item Embargo Adoption of Biogas Technology to Ordinary Pit Latrines in Uganda.(Kabale University, 2022) Kibet, BensonThe highest population of Ugandans live in rural areas.

Power quality problems have been a major concern particularly in this factory, where there are many large-scale type of motor equipment. Thus, it was useful to investigate and mitigate the power quality problems. Assessment of Power quality required the identification of any anomalous behavior on a power system, which adversely affects the normal operation of electrical motors. A power quality assessment involved gathering data resources; analyzing the data (with reference to power quality standards); then, if problems exist, a suitable recommendation or mitigation techniques was considered. Economic cost of Power Quality problems is huge particularly in this factory. The cost includes production loss, damage to expensive equipment, salary cost, restart cost. The suggested solution to the problem is depicted in the methodology where measurement of voltage, current and frequency values that helped to determine the suitable solution. Measuring instruments such as digital panel multimeter, voltmeter were used to carry out the measurements. The results are used to determine the variations in voltage, current and frequency changes. Big frequency changes and higher currents and voltages bring about shut down of the machines which stop production in the factory. Over voltage and current also causes the stress of insulation to electrical equipment and causes damage. Power quality problems i.e. the high voltages, high currents, frequency deviations have been my major concern and their impact on the industry equipment i.e. motors in particular. There were other disturbances that occurred during the survey i.e. voltage sag or voltage swell, under-voltage, temporary outage, and harmonics. Mitigation techniques were suggested to install passive harmonic filter to mitigate harmonic distortion, install a dynamic voltage restorer(DVR) to mitigate voltage disturbances and isolate all the sensitive and critical loads of kigezi highland factory feed them via uninterruptible power supplies (UPS). The research project ends with the conclusion and recommendation of the effective/economic mitigation techniques and the need for further studies.Item Restricted Assessing the Effect of Accelerators and Retarders on the Early-Age Compressive Strength of Concrete.(Kabale University, 2024) Gumoshabe, EdgarAccelerating admixtures affect the rates of reactions between cement and water to give an overall increase in the hydration rate. Retarding admixtures on the other hand slow down the hydration rate. Thus, the use of accelerators in concrete provides a shortening of setting time and/or an increase in early strength development and retarders increase the setting time and reduce early strength development. In this project, the issues of slow down and uncontrolled rapid setting and hardening of concrete or addressed by the use of accelerating and retarding admixtures (Calcium Chloride and Citric Acid respectively) in concrete. Calcium chloride and citric acid were added in four samples, with quantities of 1%, 1.5 %, 2%, and 2.5% by weight of cement, which were taken as mix -1 and mix -2. The concrete samples were tested 1, 3, 7, and 28 days of Compressive strength. The concrete specimens were laid for M25 grade of concrete.Item Restricted Assessing the Effect of Different Particle Sizes of Coarse Aggregates on Concrete Properties.(Kabale University, 2024) Ahabwe, ReinhardConcrete's compressive strength represents the hardened concrete's capacity to resist compressive loads without cracking or deforming. Duff Abrams found that concrete strength largely depends on the water-to-cement ratio. However, other factors, such as cement strength class and fineness, concrete age, curing duration, admixtures, and aggregate properties (including size, shape, texture, and strength), also significantly impact compressive strength. This study investigated how varying particle sizes of coarse aggregate affect concrete properties. Results showed that compressive strength at 28 days increased as the size of coarse aggregates decreased, with strengths recorded at 25, 23.3, 21.5, and 19.7 MPa for 10, 14, 20, and 28 mm aggregate sizes, respectively. This trend is attributed to denser packing and stronger bonding among smaller particles. Additionally, workability was found to increase with larger aggregate sizes, with slumps measured at 76, 81, 87, and 98 mm for 10, 14, 20, and 28 mm aggregates, respectively, due to larger aggregates having a lower surface-to-volume ratio, which reduces contact between aggregate particles and the cement paste.Item Restricted Assessing the Effect of Partial Replacement of Fine Aggregates in Concrete with Iron Ore Tailings in Kigezi Sub-Region.(Kabale University, 2024) Musasizi, AllanThis study aimed to assess the strength properties of concrete produced using IOT as partial replacement of the natural sand as fine aggregates. IOT is a waste product of iron ore mineral that is abundantly available in some regions and has the potential to be used as a sustainable alternative to traditional fine aggregates. In this research, the mixture, C15, was designed with 10%,25%, and 50% of IOT, natural fine aggregates and natural coarse aggregates. Properties considered included: workability, unit weight and compressive strength. Test results indicated that in all cases, IOT concrete gave high compressive strength than the conventional concrete. In conclusion, this study suggests that IOT can be used as a viable alternative to partially replace traditional fine aggregates in the production of concrete with acceptable strength properties for structural applications in pavement and floor slabs. Further research should however be carried out to investigate the durability and performance of IOT-based concrete.Item Open Access Assessing the Effect of Plastic Granules on Mechanical Properties of Clay Soil for Road Subgrade.(Kabale University, 2022) Nasasira, EzraSoi I sta bi Ii zati on can be explained as the alteration of the soil properties by chemical or physical means in order to enhance the engineering quality of the soil. The objectives of the soil stabilization were to increase the bearing capacity of the soil, its resistance to weathering process and determination of optimum plastic granules to be used which was done by use of controlled compaction. This new technique of soil stabilization can be effectively used to meet the challenges of society, to reduce the quantities of waste, producing useful material from non-useful waste materials. Plastic granules were used as a reinforcement to carry out the standard proctor compaction and CBR tests while being mixed with clay soil to improve its mechanical properties. A series of Standard proctor tests and California Bearing Ratio (CBR) tests were carried out on randomly reinforced soil by varying percentages of plastic granules (0%, 3%, 6%, 9%, 12% and 15%) by the weight of dry soil. As these materials are non-biodegradable, they have considerable life and huge potential in providing solutions to complex engineering problems. Clay soil was classified as CH or A- 7-6(16)in accordance with Unified Soil Classification System and AASHTO on a plasticity chart. The experimental results have clearly shown a significant improvement in the MDD and reduction in optimum moisture content. Finally, there was an increase in CBR values with the increase of plastic granules addition and then started to decrease and of which the optimum CBR value was determined from the graph of CBR values against percentages of plastic granules and was found out to be 3.1at 11% plastic granules addition.Item Open Access Assessing the Effect of Super Plasticizer on Scoria Concrete.(Kabale University, 2023) Turyasiima, RonaldThe objective of this research was to investigate the feasibility and effectiveness of the use of scoria, in lightweight concretes. Coarse scoria of 5/10 and 10/20 mm were used. A portion of the aggregate mixtures had an average particle size B100 l m. Scoria are often used as the constituents of structural concrete and insulating materials. The usability of the concretes tested in this study broadens as the porosity of the mixtures decreased and the cement dosage increased. According to the cement dosage and frequency types, the absorption coefficients of concretes ranged from 0.14 to 0.47. A compressive strength of 19 MPa corresponded to a density of 1800 kg/m3; compressive strengths from 10 to 18 MPa mapped to densities ranging from 1300 to 1700 kg/m3. The thermal conductivity of mixed concretes without scoria reached a maximum value of 0.268 W/m K. The thermal conductivity values of the concretes mixed without sand were below 0.403 W/m K. As sand content increased, the conductivity evolved from 0.565 to 0.657 W/m K. Freeze–thaw stability tests were conducted for 400 cycles or until specimens deteriorated.Item Restricted Assessing the Effect of Varying Temperature of Mixing Water on Properties of Concrete.(Kabale University, 2022) Muhumuza, MemoryThe aim of this research project is to assess the effect of mixing water temperature on properties of concrete. Locally available materials were used to obtain concrete cubes of 150mmx 1 50mmx 1 50mm) for every temperatures of7°C, 15°C, 22°C, 35°C and 40°C. The results of the compressive strength for both the 7days, 14days and 28days, it was observed that the compressive strength generally increases with the increase in temperatures of mixing water. It was also noticed that there was increase in the water absorption rate as temperatures increased from 7"C to 40"C of mixing water. There was increase in the density at low temperatures of 7C and 15"C of mixing water. It is observed that at higher temperatures of 35"C and 40"C the density of concrete declined. This therefore meant that the difference in densities was due to the difference in mixing water temperature. The study also revealed that mixing water temperature has a significant influence on the strength and workability.Item Restricted Assessing the Impact of Sustainable Construction Practices on Project Performance.(Kabale University, 2024) Niwahereza, BlairThe purpose of this research was to assess the impact of sustainable construction practices on project performance. Questionnaire surveys were conducted across stakeholders that included site engineers, consultants and contractors. The research categorized the proposed strategies to the implementation of sustainable construction practices using relative importance index (RII) as a basis of analysis. The most commonly used sustainable construction practices were identified as; use of local materials, use of bio-degradable materials, use of recycled materials, prefabrication and water conservation measures. Out of the 56 respondents, 16.1% were familiar with prefabrication, 14.3% were familiar with the use of bio-degradable materials, 28.6% were familiar with the use of water conservation measures, and 8.9% were familiar with the use of recycled materials and 32.1% constituted to those who were familiar with the use of local materials. The relationship between sustainable construction practices and project performance was critically determined using regression analysis and project performance was basically based on time, cost and quality. The general response from both parties were analyzed, high scored mitigation measures were discussed; awareness and education should be implemented, innovation and technology adoption; industry collaboration and partnerships, certification and standards, performance monitoring and reporting, and providing incentives were identified as the most effective strategies in implementing sustainable construction practices on construction projects. Awareness and education was ranked first with RII of 0.875, innovation and technology adoption was ranked second with RII of 0.857, industry collaboration and partnerships was ranked third with RII of 0.811, certification and standards was ranked fourth with RII of 0.807, performance monitoring and reporting was then ranked last with RII of 0.725.Item Restricted Assessing the Suitability of Recycled Concrete Material in the Production of Concrete.(Kabale University, 2020) Mumbere, CollinsThe increasing scarcity of aggregates to satisfy the high demand on construction projects has led to the need to opt for new and sustainable alternative sources of aggregates. Besides a lot of concrete waste material continues to emerge out there being disposed off with less concern for the interests of the environment. This study investigated the suitability of using recycled concrete material as potential aggregates for fresh concrete production. Hardened concrete cubes of unknown compressive strength were randomly hammered to obtain the recycled aggregates that were used for experimentation. The study entailed evaluation of several properties on the recycled aggregates obtained and the natural aggregates as controls which included the particle size distribution, aggregate crushing, moisture content, water absorption and specific gravity. Several other tests were performed on fresh and hardened concrete produced from both recycled aggregates and natural aggregates such as the slump test and compressive strength test. The percentage of replacement of the natural aggregates with the recycled aggregates was at 100%. The results obtained showed that there was a potential increase in consistency of the concrete made from both recycled coarse and fine aggregates though with a slight decrease in the compressive strength. The results obtained from concrete made from natural aggregates were slightly higher than the characteristic strengths. The study concluded that despite the deviations in the properties, recycled concrete material was suitable for production of concrete since the deviations were still within the acceptable criteria emphasized by the ministry of works and transport.Item Restricted Assessment of Cassava Peel Ash as a Partial Replacement of Cement in Plain Concrete Production.(Kabale University, 2022) Byamukama, DanThis work reports the outcome of an experiment carried out by using cassava peel ash (CPA) of varying quantities to partially replace cement in concrete work. The experiment was carried out by partially replacing cassava peel ash (CPA) of 0 to 20 percent by weight of cement at varying intervals of 2.5% and 5%. The percentage replacement used for this project was 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, 15% and 20%. The concrete was batched with a mix of 1: 1.5:3. The cubes produced were allowed to cure for 7-28 days. Compressive strength test was conducted on the samples at 7, 21 and 28 days. Slump test and setting time of the concrete cubes were conducted. The result obtained showed that compressive strength of the concrete increased with increase in length of curing age, but decreased as the percentage of CPA increases. However, the strength still remained in the allowable range of workability for concrete in line with the British standard. CPA replacement of 2.5-7.5 percentages was found to be suitable considering the strength and safe use of the concrete. It was concluded that CPA replacement of 2.5%, 5%, 7.5% showed no significant loss in strength compared to the control sample and is stable and could be acceptable in most concrete works and other percentage replacements up to 20% can be used for light structures. At the long run cassava peeling that currently constitutes waste concern in south western Uganda can best be managed through alternative use.Item Open Access Assessment of Strength Properties of Concrete Produced Using Scoria as Coarse Aggregates.(Kabale University, 2023) Kasozi, ChrisestomThis study aimed to assess the strength properties of concrete produced using scoria as coarse aggregates. Scoria is a volcanic rock that is abundantly available in some regions and has the potential to be used as a sustainable alternative to traditional coarse aggregates. In this research, three concrete mixtures, C25, C30 and C35 were designed with 100% of scoria as coarse aggregates and natural fine aggregates. Properties considered included: workability, unit weight and compressive strength. Test results indicated that developing scoria-based concretes using locally available Scoria lightweight aggregates seems to be feasible. The findings showed that in all cases, scoria concrete gave lesser compressive strength than would be expected from the conventional concrete. The compressive strength curves plotted for the scoria concrete mixes developed in this investigation were comparable to typical compressive strength curves for normal weight concrete with relatively better capacity at failure than scoria concrete. In conclusion, this study suggests that scoria can be used as a viable alternative to traditional coarse aggregates in the production of concrete with acceptable strength properties for structural applications in floor slabs. Further research should however be carried out to investigate the long-term durability and performance of scoria-based concrete and to study its microstructure.Item Restricted Assessment of the Efficiency and Effectiveness of Waste Water Treatment and Management Systems in Kabale Municipality.(Kabale University, 2020) Muyambi, AmosWaste water treatment is the process of removing contaminants from the waste water or sewage and convert it into an effluent that can be returned to the water cycle with acceptable impact on the environment or reused for various purposes.

It was based on the following objectives; To identify branding strategy that fits and is specific for gorilla trek camp, to implement the strategies, evaluating if the strategies implemented can work out. A descriptive survey design was used whereas questionnaires and interviews were used to gather data from the respondents. The study findings indicate that business cards, custom t-shirts, aprons, meal menus, brochures, stickers and calendars are commonly used as branding tools in gorilla trek cam while electronic advertising, is rarely used as a branding tool in gorilla trek camp. Improving the brand identity and creating a wide market are the roles of branding in gorilla trek camp. The researcher recommended that the management of gorilla trek camp should plan about embracing such branding strategies like introducing custom t-shirts and identity cards for workers. They should further introduce business cards to distribute to clients in order for the loyal clients to spread the business brand to other people, and more to that they should introduce a logo for the company such that it can be easily identified.Item Restricted Characterization of Soil Properties and the Implications for Landslide Occurrence in Rubanda District.(Kabale University, 2021) Ainamaani, SamuelSoil properties of major landslides that occurred on Tuesday 26th September 2017were analysed. A mudflow washed away Mfasha trading Centre, which hosts people mostly from Bufundi and Muko sub counties. In order to test the hypothesis that ‘soils at the landslide site are particularly ‘problem soils’ and thus prone to landslides’, the following analyses were undertaken: Dynamic Cone Penetration Test (DCP), particle size distribution and Atterberg limits. The liquid limits for all the test pits were all above the threshold of 25% indicating high expansion potential of the soils in this area. And from the plasticity charts the PI and LL results reveals that the soils are clay of high plasticity and this signals chances of landslides Soil particle distribution The clay fraction for the soil were above 10% threshold identified from the analysis of the soil samples from the respective test pits as shown in the table below, this explains higher possibilities of extreme expansion potential and hence susceptible to land slides The bearing capacity of soil was determined as 250.825 kN/M3.When compared with the safe Safe/allowable bearing capacity of Soft rock 440kN/M3, the bearing capacity of soil is too low indicating high chance of collapsible soil.
