## Aggregate Crushing Value Test Step By Step Procedure

Aggregate Crushing Value Test Step By Step Procedure Aggregate crushing value test is done the find the actual crushing value of aggregate we need to carry out this test to find out how much resistance does the aggregate has against the surface abrasion under traffic to find out how much resistance does the aggregate can withstand under the roller during construction to determine the strength Aggregate Crushing Value Significance Test Procedure The primary purpose of using coarse aggregates is to enhance the strength of the concrete moreover the coarse aggregates will easily blend with other concrete ingredients and make it as a homogeneous element test procedure the aggregates crushing value test Aggregate Crushing Value Test Procedure And Result For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner this testing method is known as an aggregate crushing value test aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load
