A Review on Study of Partial Replacement of Fine Aggregate with Crumb Rubber and Coarse Aggregate with Steel Slag Aggregate

Steel slag and crumb rubber are industrial byproducts that have disposal issues and pose a threat to the environment. aggregates are in demand in concrete consumption is rising quickly along with the construction industry. These two materials are crucial in the search for future aggregate alternatives. Concrete that is typically fragile has been given a boost in impact resistance and hardness using crumb rubber. Because regular concrete is prone to failure from fatigue and impact loads, rubber aggregates’ flexibility may hold the key to finding a solution. Even though crumb rubber concrete’s mechanical characteristics have slightly decreased, this can be fixed by properly treating the crumb rubber aggregates. Crumb rubber aggregates could be treated using techniques including mechanical, chemical, thermal, and microwave treatment to improve their adhesion to the cement mortar. In this study, steel slag aggregate was used to substitute natural coarse aggregate to varying degrees (10%, 20%, 30%, and 40%), in order to determine the obtained optimal value of steel slag utilised concrete replaces a portion of the natural fine aggregate and the fine aggregate at varied ratios of 5%, 10%, and 15% with crumb rubber. The compressive strength, split tensile strength, and flexural strength of concrete of grade M30 were tested. The outcomes were contrasted with traditional concrete.
