Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied,

Theory Aggregate Crushing Value Test Of Aggregate. The apparatus of the aggregate impact value test consists of a testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter level and plane concrete floor of minimum 45 cm thickness are used to support it

30/03/2020· Procedure of Aggregate Crushing Value Test:-. Sieve the test material through 12.5 mm and 10.0 mm IS sieve. Take test samples of aggregates passing through 12.5 mm IS sieve and retained on 10 mm IS sieve (minimum 3 Kg). Dry theme in an oven for 4 hours at a temperature of 100 °C to 110 °C and then cool at room temperature.

27/08/2019· (Aggregate Crushing Value Test) b) To assess suitability of aggregates for use in different types of concrete and pavements. Theory and Scope. The road aggregate is generally manufactured to a specified grading and stock piled at a sight. Before being used in the pavement it undergoes certain operations as loading and transporting in trucks, tipping, spreading and

18/07/2021· Aggregate crushing value test codes. Following are the standard guidelines for the crushing value test on the aggregates: • IS 2386 (Part 4):1963 • BS 812–110:1990. Objective. The objective of this test is to: 1. Determine the aggregate crushing value of coarse aggregate 2. Check the suitability of coarse aggregates to use in different types of road .
