Get PriceThe tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the ﬂexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality. Normal values for ACV range from 14 to 30%, and for

Get PriceStrength is a measure of the ability of an aggregate particle to stand up to pulling or crushing forces. Elasticity measures the "stretch" in a particle. High strength and elasticity are desirable in aggregate base and surface courses. These qualities minimize the rate of disi ntegration and maximize the stability of the compacted material. The ...
