The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load .
Oct 09, 2018· However, it can be explain as the aggregate crushing value which is defined as a ratio of the weight, of fines passing the specified sieve to the total weight of the sample expressed as a percentage. The value is usually recorded up to the first.
Sep 05, 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.
Aggregate crushing Value (percent)=w2/w1*100 Aggregate crushing value = W2/W1 * 100 = 771/2917 * 100 = % RECOMMENDED VALUES The suitability of aggregate is adjudged, depending on its proposed use inthe pavement layers. Specified limits of percent aggregate crushing value for different types of road construction s given bellow.
Jan 23, 2018· The aggregate crushing value for cement concrete pavement shall not exceed 30%. The aggregate crushing value for wearing surfaces shall not exceed 45%. PURPOSE OF TEST: The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load.
