• Aggregate Impact Value Test Procedure As Per Is 2386 Part

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2 W1) x 100 Lab Report.Gravity of coarse aggregate was determined as 2.309. It was 13 reduce from standard value 2.67 which is in the range from 2.5 to 3.0. The Specific gravity of fine aggregate was also accurate. E. Aggregate Crushing value test This test was performed as per IS 2386 (Part IV) – 1963. The crushing value of RCA was 20 .
