Coarse Aggregate: Coarse aggregate is obtained by crushing quarry rock to required size. The pieces of crushed stone varying from 5mm to 80mm size can be called coarse aggregates. The size of the aggregate that is to be used depends on the type of work. Most of the times 20mm to 40mm size aggregates are used in R.C Works.
