Aggregate Crushing Value Test Cement Concrete
Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates areA lower crushing value indicates a lower crushing fraction under a specific load and would give a better result, longer service life and economic performance Aggregate crushing value test codes Following are the standard guidelines for the crushing value test on the aggregates: • IS 2386 (Part 4):1963 • BS 812–110:1990 Objective TheCrushing Value Test of Aggregates Civil Bull
Aggregate Crushing Value Test The Constructor
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions2 天前The aggregates crushing value test should be performed as per IS code 2386 Part IV First, fill the sample aggregate with onethird of the cylindrical measure in three layers Each layer should be tamped 25times freely After filling the sample aggregate, weigh and record it as W1 Now fill the aggregate in the mould along with the plunger onAggregate Crushing Value – Significance & Test Procedure
