Aggregate crushing value apparatus is used for measuring of resistance of aggregate to crushing. Specification: . consists of m.S.Cylindrical container 150 mm ±0.5mm dia x 130mm to 140mm high with base plate 200 to 230 mm./SGR x 6mm thick.
3 2 Wet test 3.2.1 Preparation of the test sample The same as in 3.1.1. 3.2.2 Filling the cylinder Proceed as in 3.1.2. When the mass of the aggregate has been determined, the aggregate is immersed in water for 24 h. After soaking, take the aggregate out, allow to drain for 5 minutes, and then surface-dry it by rolling it in a damp cloth.
