allowable aggregate crushing value

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. Aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, As an alternative to

    Aggregate Crushing Value Test Procedure And Result

    The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined ...
