In recent years, the utilization of waste products has increased, as a small step in the usage of waste like rubber tires is thrown out for construction purposes. The rubber tires are made into required aggregate sizes called crumb rubber and replaced in place of aggregate works. This will be very easy to use, economical, and easy-to-use crumb rubber. The objective of this study is to examine the impact of partially replacing the fine aggregate in concrete with crumb rubber, specifically in sizes ranging from 4.75 mm to less than 0.075 mm. The replacement percentages tested were 5, 10, and 15%. The mechanical properties of M25 grade concrete were evaluated by testing two specific properties of rubberized concrete: compressive strength, flexural strength, and split tensile strength. We recorded and analyzed the results of these tests. We conducted a comparative analysis of the compressive strength, split tensile strength, and flexural strength of concrete mixes containing 5, 10, and 15% of a certain ingredient, and found that the 5% mix performed better than the other variations. The findings indicated that the compressive strength of concrete made from waste tire rubber was significantly lower than that of regular concrete. However, concrete incorporating waste tire rubber exhibited ductile and plastic behavior.
