30/10/2015 · This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone brick khoa of aggregates.
