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 Restricted Enhancing Plasticity and Compaction Properties of Clay Soil- Subgrade Using Iron Ore Tailings: A Case Study of Kabale District.(Kabale University, 2024) Mukago, AndrewThe workability of any soil, when used as a construction material, is greatly affected by its plasticity and compaction characteristics. Investigating the Effect of Iron Ore Tailings on the Plasticity and Compaction Properties of Clay Soils" aimed to explore the potential impact of iron ore tailings on the engineering properties of clay soils. Clay soils are widely used in construction and civil engineering projects, but their plasticity and compaction properties can vary significantly depending on their composition and environmental factors. This project sought to evaluate how iron ore tailings interact with clay soil samples and influence the soil's mechanical behavior by introducing them. Iron ore tailings are waste generated during the mineral processing process and are the main component of industrial solid waste. If not properly treated, Iron ore tailings cause many hazards such as land occupation, environmental pollution, and safety hazards among others. Despite the abundance of clay soils in construction projects, their plasticity and compaction properties can be detrimental to structural integrity. The main objective of this research was to enhance the plasticity and compaction properties of clay soil subgrade using iron ore tailings and the specific objectives were to determine the physical and mechanical properties of Iron Ore Tailings and Clay, study the change in the; plasticity of clay soils at different percentages of Iron Ore Tailing’s Content (10%, 20% and 30%), compaction property of clay soils at different percentages of Iron Ore Tailing’s Content and to determine the minimum percentage that gives a positive change in the enhancement of plasticity and compaction properties of clay. Tests like particle size distribution analysis, natural moisture content, and Atterberg limits were carried out to classify, determine the amount of water naturally present in samples, and determine the plasticity index of the soil and iron ore tailings, respectively. Tests like specific gravity and water absorption, MDD, and CBR were carried out on clay soil and the IOT samples to extensively know their physical compaction characteristics. From the CBR test for clay (which served as the control experiment); the moisture content of 12.7% before compacting was obtained. The swell values of the sample of 0.13%, 0.09%, and Enhancing Plasticity and Compaction Properties of Clay Soil- Subgrade Using Iron Ore Tailings. (case study: Kabale district) 0.03% for light compaction, medium compaction, and heavy compaction respectively were obtained. The CBR values obtained at 2.5mm penetration were 3.5%, 4.4%, and 7.8% for light, medium, and heavy compaction respectively; at 5.0mm penetration were 3.3%, 4.1%, and 6.9% for light, medium, and heavy compaction respectively. CBR values of 3.7%, 5.0%, and 5.9% for 90%MDD, 93%MDD, and 95%MDD respectively were obtained.Item Open Access Investigating a Suitable Ratio of Iron Ore Tailings and Quarry Dust in Concrete Production.(Kabale University, 2024) Kasozi, MarkConcrete is the most widely used construction material, man consumes no material except water in such a tremendous quantity. Concrete is a homogeneous mixture of cement, coarse and fine aggregates, and water which consolidates into hard mass due to the chemical reaction between the cement and water, but its production has significant environmental consequences, including high carbon emissions and natural resource depletion. As a result, there is an increasing interest in the development of sustainable concrete technologies that reduce concrete's environmental footprint while maintaining its performance and durability. Sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Iron ore tailings are the residual materials left over after the extraction of iron ore from its ore body on the other hand quarry dust is a fine-grained material produced as a by-product of quarrying operations. It is typically composed of crushed stone, sand, and other mineral particles. The main objective of this study is to investigate a suitable ratio of iron ore tailings and quarry dust in concrete production by determining the physical properties of fine aggregate, designing a concrete mix conducting mechanical tests, and conducting a comparative study between the effect of Buhara IOT and Ntungoma quarry dust. IOT gives a Cu of 6.3 and quarry dust a Cu of 7.5 and they are both greater than 4 implying that both are well-graded materials. Higher values of Cu imply that D60 is significantly larger than D10. This means that both larger and smaller particles a present in significant quantities. The fineness modulus of quarry dust is 3 and that of IOT is 3.5 implying that IOT has a higher percentage of coarse particles. IOT particles produced a higher density than both quarry dust particles and coarse aggregates combined. Quarry dust had a greater water absorption than iron ore tailings because it had more quantities of finer aggregates than iron tailings making it absorb more water. workability increased with an increase in the percentage of quarry dust and at 80% quarry dust and 20% IOT obtained the highest slump value of 35mm, Compressive strength increased with an increase in quarry dust percentages. Maximum percentage was obtained at 80% quarry dust and 20% IOT. At 28 days we obtained the maximum compressive strength of 19Mpa.
