For weak aggregates, the required load for thefirst ten per cent fines test can be estimated by means of the formula:7 Lab Test on Aggregate Should Satisfy for Use in Concrete,The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing,purpose of aggregate crushing value - ME Mining,The purpose of aggregate crushing value test. Aggregate Crushing Value Test Determine Aggregate. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction isWhat is the significance of ten percent fines value in,,This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
