Abstract
Abstract. Self-compacting concrete, which is characterized by its capacity to flow, can also consolidate under its weight. Hardened concrete from concrete building demolition can be used to partially replace natural coarse aggregate in self-compacting concrete. The current study compares the properties of self-compacting concrete with 0 percent, 25%, 50%, 75%, and 100% substitution of recycled coarse aggregate in the fresh and hardened states. The evolution of passing ability properties using the L-box test, filling ability properties using the slump cone test, and segregation properties using the V-funnel test are also included. Compression, tension, and flexural strength are all checked for hardened properties. Rapid chloride permeability and sorptivity tests are used to assess durability. The experimental program revealed that at RCA utilization levels of 25% to 50%, little to no negative impact on power, workability, or durability properties was observed.

This study aims to fill a significant gap in the current literature by investigating the versatile properties of self-compacting concrete (SCC) with characteristic coarse total subbed with RCA at levels of 0%, 25%, half, 75%, and 100%
Sorptivity x 10-6 mm/ min Rate of Absorption I mm Conclusion The research paper contributed to the current SCC literature by examining the effects of different levels of RCA integration on workability, strength, and, most importantly, durability
Summary
The use of sustainable materials has become increasingly common in recent years. By that the use of nonrenewable natural resources, sustainability benefits the ecosystem. The use of sustainable materials has become increasingly common in recent years [1]. A few investigations have investigated the utilization of reused materials in the assembling interaction [2]. The utilization of reused totals in the creation of new cement seems to have a great deal of guarantee. It considers the goal of issues identified with the assortment, transportation, and removal of building and destruction squander, just as adding to a conceivably more feasible environment through an improvement in the estimation of such squanders, lessening the utilization of common aggregate [3]. It can be difficult to ensure that the formwork is properly stacked, that is, completely compacted without voids or honeycombs, when a large amount of generous assistance is to be put in a shaped cement (RC) section
