2020/04/13· The shape of these aggregate is round, angular or irregular and due to lower surface area rounded aggregate has the lowest water demand and also requires lower mortar paste. To yield the most economical mixes of concrete grades up to M35 these properties make rounded aggregates and in favor of angular aggregate with more surface area the possibility of bond failure would tilt the balance for a

The effects of the properties of coarse aggregates on the

A rounded aggregate will, for example, give concrete of higher workability than all angular aggregate. Thirteen coarse aggregates were investigated to determine the effects of their shape, surface texture and water absorptive capacity on the workability of concrete.
