ABSTRACT
Waste management is the first priority for many countries, so the focus of research is on using waste materials in concrete as filler as well as substitution for concrete ingredients such as crumb rubber for fine aggregates. Crumb rubber results in a reduction in strength properties, to overcome this issue, the addition of strength-increasing waste materials as cement substitution is investigated along with crumb rubber (5%, 10%, and 15%) as fine aggregates. the Different mixes of Waste glass powder and silica fume were substituted with 10% of cement and a combined 5-5% percentage of silica fume and waste glass powder is considered. The various parameters were considered to appraise the application of waste materials in concrete. The main aim is to find the best materials from SF and WGP to enhance rubberized concrete's properties. The concrete is compared with both materials used and control concrete and crumb rubber concrete for the properties like workability, compressive strength, tensile strength, density, ultrasonic pulse velocity, and dynamic modulus of elasticity. It has been seen that silica fumes enhanced the properties of rubberized concrete better as compared to waste glass powder. The 10% of silica fumes along with 5% crumb rubber enhanced the compressive strength by 11% of the strength of Rubberized concrete without silica fumes. Similarly, 10% of waste glass powder along with 5% of crumb rubber enhanced the compressive strength by 6% of the strength of rubberized concrete. The concrete silica fume and crumb rubber gave the best 28th day test results as compared to other concrete with waste glass powder and combine silica fume and glass powder.
