Jul 01, 2017 · There is a general belief that crushed aggregates contribute higher strength in concreting compared to rounded aggregates. Contrary to this belief, our study revealed: rounded aggregates perform better than crushed aggregates because the rounded shape which considered as a negative characteristic is compensated by improving the workability and reducing the need of mixing water,
