The effect of recycled coarse aggregate (RCA) on the fresh and hardened properties of C40 self-compacting concrete (SCC) was investigated in this paper. The slump. T 500 (the time needed for SCC to spread into a round configuration with a nominal diameter of 500 mm). the slump flow and the flow time of fresh C40 SCC as well as the compressive strength and modulus of elasticity of hard... https://www.spidertattooz.com/Air-Force-Embroidered-Badge-USAF-Honor-Guard-Master-OCP/
