Concrete mix ratio is a relative proportioning of cement, sand, aggregate and other materials needed to prepare different grades of concrete. For example, the prescribed Nominal concrete mix ratio of M20 concrete is 1:1.5:3, hence for every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate, in volume, is needed to prepare M20 gradeget price

Aggregates Cement

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.get price
