CHAPTER 4 STRENGTH TEST USED FOR CRUSHED AGGREGATES

Two methods are used to test aggregate in two different conditions. 1. Aggregate in dry condition . 2. Aggregate in wet condition (Socked) Both methods are applicable to aggregates between the sizes of 14mm - 2.36mm. Normally in Sri Lanka, a sample with the crushing aggregate in between 14mm sieve passing and 10mm sieve retaining can be prepared.
