Aggregate Crushing Value Test Report Discussion Malaysia. Aggregate crushing value test report result concl aggregate crushing value test safety precaution Concrete Wikipedia Concrete usually Portland cement concrete is a posite material posed of fine and coarse aggregate.
Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
The standard aggregate crushing test is done on aggregates passing 12.5 mm sieve and retained on 10 mm sieve and make those surface dry by heating at 11 to 110°C for four hours and cooled to room temperature. Surface dry aggregates are filled into the standard cylinder in three-layer. Each layer should be tamped 25 times, finally levelled off using a tamping rod as the straight edge.
The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in
