·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 An
DETERMINATION OF AGGREGATE IMPACT VALUE AIV BS 812 112 Scope This Part of BS 812 describes methods for the determination of the aggregate impact value AIV which gives a relative measure of the resistance of an aggregate to sudden shock or impact Principle A test specimen is compacted in a standardized manner into an open steel cup
·construction is the ability of the aggregate to resist crushing The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a gradually applied compressive load Scope The particular purpose which an aggregate is meant to serve requires the aggregate to have a particular strength This
