Study on Properties of Self-Compacting Concrete Prepared with Coarse Recycled Concrete Aggregate

Article Preview

Abstract:

Self-compacting concrete is absent of vibration noise during casting, improves the construction efficiency, and provides a healthier working environment compared to the traditional vibrated concrete. The potential coarse recycled aggregate obtained from crushed concrete for making self-compacting concrete was considered to replace the aggregate with the percentage of substitution of recycled coarse aggregate 0%, 50% and 100%. Thus, three types of concrete mixtures were made. Experiments show that, the properties of these concrete only have slight differences and recycled coarse aggregate can be successfully used for the preparation of self-compacting concrete. The method solves the problem of the waste disposal by the demolition of old buildings.
