crushing value for ordinary concrete


Posted on November 15, 2018



crushing value for ordinary concrete,Aggregate Crushing Value Test -Determine Aggregate Crushing .May 5, 2010 . Aggregate crushing value test provides strength of aggregates for resistance against crushing under loads and is used for roads and pavements construction.crushing value for ordinary concrete,Aggregate Crushing Value Testtraffic wheel loads. If the aggregates are weak, the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load.
