The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An ...

Feb 15, 2019 Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

Dec 19, 2019 If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

Aggregates with low specific gravity value are mostly weaker than those with higher specific gravity values. Water Absorption Water absorption of aggregates is the % of water absorbed by an air-dried aggregate when immersed in water at 27C for a period of 24 hours.
