Aggregate Crushing Value Test Procedure And Result

Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing a cylindrical shape specimens of size 25 mm diameter and 25 mm height. This cylinder is subjected to compressive stress. Depending on the type of parent rock gives different compressive strength varying from a minimum of about 45 MPa to a maximum of 545

Aggregate Crushing Value Test L & T Learning Technology

The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a

DETERMINATION OF AGGREGATE CRUSHING VALUE

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3.

Aggregate Impact Value Test, Procedure, Result & Standards

Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact Value)
