Explanation: Crushing test: This test is carried out to assess the strength of coarse aggregate when a compressive load is gradually applied. The test is carried out as follows: 1. The sample is broken into chips passing a 12.5 mm I.S. sieve and retained on a 10 mm I.S. sieve. 2. The material is heated to a temperature of 100°C to 110°C and it is then cooled to make it …

This test seeks to determine the amount of force required to produce 10% of fine values, which is expressed as the weight of fine aggregates divided by the weight of all aggregates multiplied by 100 (i.e., weight of fines aggregates/weight of all aggregates x 100 = 10%). This test is similar to the Aggregate Crushing Test (ACV), which applies a ...

In this test, the aggregate's resistance is determined to crushing under gradually applied compressive load. a) IS codes for Crushing value Test: IS 2386(Part 4):1963; BS 812–110:1990
The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing value. Impact test – determines the resistance of aggregates to impact forces. Multiple layers of sieved samples are tamped 25 times before a 14 kg hammer is dropped for a total of 15 blows. The resultant sample is sieved ...
