  • Recycled Concrete Aggregate an overview | ScienceDirect

    Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent For instance, British standard BS 85002 ( BSI, 2006 ) defines RCA as recycled aggregate with maximum masonry/fines content of 5%, maximum lightweight material/asphalt content of 05% and maximum other foreign01/06/2006· Recycled concrete aggregates are different from natural aggregates and concrete made from them has specific properties The percentages of recycled concrete aggregates were varied and it was observed that properties such as compressive strength showed a decrease of up to 10% as the percentage of recycled concrete aggregates increased Water absorption of recycled aggregatesStudies on recycled aggregatesbased concrete MajorRecycled aggregate concrete is in close proximity to normal concrete in terms of split tensile strength The slump of recycled aggregate concrete is more than the normal concrete At the end , it can be said that the RCA upto 50 % can be used for obtaining good quality concrete MATERIALS International Journal of Pure and Applied Mathematics Special Issue 3243 Concrete is a composite materialA STUDY ON RECYCLED CONCRETE AGGREGATES
