What is Recycled Aggregate Concrete?

 · Uses of Recycled Aggregate: – Building the base of a road. The underlying layer forms a structural foundation for paving. – Ready mix concrete. This is a mix of water, sand and cement. It can substitute for the brandnew aggregate. This includes uses for walkways, residential streets and concrete paving. – Stabilizing the soil.

Concrete Recycled Aggregate

Recycled concrete used as coarse aggregate in new concrete possesses some potential for alkalisilicareaction if the old concrete contained alkalireactive aggregate. The alkali content of the cement used in the old concrete has little effect on expansion due to alkalisilicareaction.
