dc.contributor.author	One of the most adaptable and commonly utilized building materials in the global construction sector is concrete. Fine and coarse aggregate make about 65-75% by volume of concrete production. Fine aggregates makes up between thirty and forty percent of this volume. This study is a focus on investigating the partial replacement of waste glass for fine aggregate in concrete production and to determine the optimal replacement of sand with waste glass. Fine aggregate in concrete mix conducted replaced with glass waste of 10%- 50% with an interval of 10%. Mix design is by ACI 211.1 and design strength of 30MPa is used. Nine cubes without waste glass and forty-five cubes with waste glass were cast in total to partially replace the fine aggregate. The cube samples of concrete were allowed to cure for 7, 14 and 28 days before being evaluated for compressive strength. A water /cement ratio of 0.51 was employed. An X-ray diffraction, scanning electron microscopy, water permeability, water absorption, carbonation, unit weight, compressive strength, flexural strength, tensile strength, and ultrasonic pulse velocity program were used in the experiment. It can be percentage of waste glass content increases; Unit weight, water absorption and carbonation depth also increases and the workability of concrete is increases. The optimal replacement percentages for maximum compressive strength, flexural strength, and splitting tensile strength were found to be 40%, 40%, and 30% respectively. The use of waste glass as a partial replacement for natural sand in concrete can have several benefits. It can improve workability, reduce unit weight, and enhance compressive, flexural, and splitting tensile strength. However, it is crucial to carefully consider the optimal replacement percentage based on specific project requirements and performance criteri

dc.description.abstract	Concrete is a composite of aggregates and binders. The ingredients of concrete included an expensive and environmentally unfriendly element, namely cement, which is an ecologically unfriendly process due to the ejection of CO2 gas into the atmosphere and ecological degradation. Hence, this study assesses the suitability of blended ash (Sugarcane Bagasse Ash and Saw Dust Ash) as a partial replacement for cement in C-25 concrete production. Sugarcane Bagasse Ash (SBA) is a sugar factory by-product and Sawdust (SD) by-product of Sawmill. To fulfill the aim of this investigation test the physical attributes and chemical composition of blended ash (sugarcane bagasse ash and sawdust ash), the workability of freshly produced concrete, mechanical characteristics, and microstructural analysis of hardened concrete. After analyzing the blended ash's chemical constituents, it was determined that 50.34% of the ash's total SiO2, Al2O3, and Fe2O3 content designated it as class C pozzolana. The compressive strength test result showed that blended ash replacing 10% of the cement exhibited a 4.76% improvement in compressive strength compared to the control concrete. Scanning electron microscopy (SEM) analysis and X-ray diffraction (XRD) microstructure tests also demonstrate the enhanced blended ash replacement performance. As a result, 10% blended ash is the ultimate replacement quantity as similar to those of the control mix property	en_US
