摘要

Sand that is produced by depleting natural resources in order to produce concrete in compliance with production requirements is becoming more and more available. In order to use waste tyre aggregate (WT) in the construction sector and lower the aggregate content. This serves as the foundation for sustainable manufacturing and the preservation of the environment. The investigation maintains a constant water/binder ratio of 0.40 and a binder dosage of 530 kg/m3. Sand and cement are substituted for waste tyre and silica fume (SF) in the amounts of 10% and 15% by volume and 15% by weight, respectively. This makes it feasible for the evaluation of the compressive strength, slump flow, and V-funnel of SCC mixes. The SCC’s compressive strength was measured after a 28-day curing time. According to test results, WT replacement concrete has each of these characteristics and can be utilized in civil engineering.
