Reporting of Results – The mean of the two results shall be reported to the nearest whole number as the aggregate impact value of the tested material.
This test, prescribed by BS 812: Part 110:1990, assesses the resistance of an aggregate to crushing, indicating its ability to withstand compressive loads.
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 …
