Classification of Aggregates Based on Size and Shape

22-7-2016Classification of Aggregates Based on Shape We know that aggregate is derived from naturally occurring rocks by blasting or crushing etc so it is difficult to attain required shape of aggregate But the shape of aggregate will affect the workability of concrete So we should take care about the shape of aggregate Get price
