Adoption of Biogas Technology to Ordinary Pit Latrines in Uganda.
(2022) Kibet Benson
The highest population of Ugandans live in rural areas. 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.

Analysis of Power Quality Issues in Induction Motors.
(Kabale University, 2021) Nazziwa, Evalyne
This project is about the analysis of power quality issues in induction motor machines that was carried out at Kigezi highland tea factory. 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.
Assessing the Effect of Plastic Granules on Mechanical Properties of Clay Soil for Road Subgrade.
(Kabale University, 2022) Nasasira, Ezra
Soi 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.
Assessing the Effect of Super Plasticizer on Scoria Concrete.
(Kabale University, 2023) Turyasiima, Ronald
The 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.
Assessing the Effect of Varying Temperature of Mixing Water on Properties of Concrete.
(Kabale University, 2022) Muhumuza, Memory
The 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.
Assessing the Suitability of Recycled Concrete Material in the Production of Concrete.
(Kabale University, 2020) Mumbere, Collins
The 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.
Assessment of Cassava Peel Ash as a Partial Replacement of Cement in Plain Concrete Production.
(Kabale University, 2022) Byamukama, Dan
This 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.
Assessment of Strength Properties of Concrete Produced Using Scoria as Coarse Aggregates.
(Kabale University, 2023) Kasozi, Chrisestom
This 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.

(Kabale University, 2019) Asiimwe, Elton
The study was about the effects of branding as a tool advertising in gorilla trek camp hotel in kabale town. 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.
Characterization of Soil Properties and the Implications for Landslide Occurrence in Rubanda District.
(Kabale University, 2021) Ainamaani, Samuel
Soil 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.
Characterization of Scoria Rock from Kisoro As an Aggregate in Concrete.
(Kabale University, 2023) Ayebale, Sam
Numerous volcanic scoria (VS) cones are found in many places of the world. Many of them have not yet been investigated, although few have been used as binders, floor beds and aggregates in lightweight concrete for a very long time. The use of scoria aggregates could be considered as a common practice in the construction industry due to the related economic, ecologic and performance benefits. This research study highlights the characteristics of scoria rock from Kisoro as aggregates. The tests on both fine and coarse aggregates from scoria rock are presented in this report. The test results on the engineering properties of scoria revealed that the material is suitable to be used as a fine aggregate and coarse aggregate as they were found to be acceptable by ASTM standards these are particle size distribution, shape classification, fineness modulus, silt content and organic impurities. The other physical properties of the scoria such as bulk density, specific gravity and absorption indicated that samples from Kisoro gave acceptable results.

Cost Analysis of Reclaimed Asphalt Concrete for Rigid Pavement Construction.
(Kabale University, 2023) Ariho, Dan
This study evaluated the feasibility and cost effectiveness of using reclaimed asphalt (RAP) as aggregates in production of concrete for rigid pavements. The RAP material was obtained from Kabaraga in Kabale along Kabale-Mbarara highway crushed to obtain the desired sizes and subjected to laboratory tests i.e. particle size distribution, bulk density and relative density for both coarse and fine aggregates. Concrete samples of nominal mixes1:3:6 and 1:2:4 at varying water cement ratios of 0.4, 0.5 and 0.6 were prepared and tested for slump. 15 concrete cubes of 150mm x 150 mm x 150 mm per concrete mix per w/c ratio were cast and subjected to curing under water after 24 hours of casting. The cubes were then tested for compressive strength after 3, 7, 14, 28 and 56 days of curing and a minimum of 3 cubes were crushed and results recorded. The results analysis for compressive strength indicates that there was a progressive increase in compressive strength at different curing days for both RAP and normal concrete, having the highest values at 56 days of 10.800, 15.900 and 13.170 Mpa for a 1:2:4 mix of conventional concrete at 0.4, 0.5 and 0.6 water cement ratios and 4.923, 8.290 and 8.067 Mpa for 1:3:6 mixes of 0.4, 0.5 and 0.6 respectively. While for RAP concrete compressive strength at 56 days were, 5.367, 6.003 and 9.533Mpa for 1:2:4 and 3.767, 4.750 and 5.367 Mpa for 1:3:6 mix at 0.4, 0.5 and 0.6 water cement ratios respectively. A unit cost analysis for producing a m3 of RAP concrete and normal concrete showed that, utilization of RAP as aggregates in production of 1m3 of concrete will yield a cost saving of about 20% and 14% resulting from the use of RAP in production of concrete for mixes 1:3:6 and 1:2:4 respectively. It was therefore concluded that, concrete produced with RAP aggregates at 1:2:4 w/c ratio of 0.5 can be used for rigid pavement construction of low traffic and pedestrian walk-ways based on strength and cost criterion.
