Recycled Concrete Aggregate an overview ScienceDirect

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

Plastic Mixed Reinforced Concrete Behaviour

The mix proportion used in the present investigation was 1:1.5:3 with water cement ratio of 0.5. The ingredients of the concrete viz. cement, sand and aggregate were weighed and mixed dry. To this dry mix the calculated quantity of road wastes (and raw plastics) were added and the mixing was continued till a homogeneous mix was obtained.

Aggregate Properties You Need to Know: Strength

Construction aggregates are mineral materials used in the production of construction materials such as Portland cement concrete and hot-mix asphalt, and as unbound base courses for pavements. In their primary role as filler in these materials, the volume of aggregates can take up 90 95% of asphalt and 70 80% of concrete

WHAT ARE THE PROPERTIES OF AGGREGATES FOR CONCRETE

Oct 01, 2016· For the preparation of economical concrete mix on should use largest coarse aggregates feasible for the structure. IS-456 suggests following recommendation to decide the maximum size of coarse aggregate to be used in P.C.C & R.C.C mix. Maximum size of aggregate should be less than. One-fourth of the minimum dimension of the concrete
