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.

4/1/2014 Procedure of testing Aggregate Crushing Value (ACV): 1. Make a sieve analysis and get sufficient amount of aggregate by using 14.0 mm passing sieve and 10.00 mm retained sieve. 2. After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm. 3.

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.
