    Fresh Properties Of Selfcompacting Concrete With Coarse

    Fresh Properties of SelfCompacting Concrete with Coarse.In this paper, the fresh properties of self-compacting concrete SCC using recycled coarse aggregate RCA were evaluated. Five types of SCC mixtures were made, where the percentage of substitution of natural coarse aggregate by RCA was 0, 25, 50, 75 and 100. The cement content, water to binder WB ratio and Superplasticizer dosage were kept the same for all mixes.

The Materials used in SCC are the same as in conventional concrete except that an excess of fine material and chemical admixtures are used. Also, a viscosity-modifying agentVMA will be required because slight variations in the amount of water or in the proportions of aggregate and sand will make the SCC unstable, that is, water or slurry may separate from the remaining material.
