Aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, As an alternative to crushing value, the aggregate impact value should not exceed 45% by weight for aggregates used for concrete other than for wearing surfaces and 30% by weight for concrete for wearing surfaces, such as runways, roadsWhen the silt, clay dust, or mud is recent and has not been the resistance by washing, it might generate mini strength concrete [13].The value of aggregate crushing is a comparative measure of a(PDF) RELATIONSHIP BETWEEN AGGREGATE
