Effect of Aggregates on the Properties of Concrete

It is judged by the surface of a crushed concrete. If in a crushed concrete specimen, larger numbers of aggregate particles are seen pulled out from their sockets and some of them seen fractured or broken right through, then the bond is called good. Greater number of crushed aggregate particle suggests weaker aggregate. Get price
