ContactCrushing Value Test Procedure Select clean and dry aggregate passing through 12.5 mm and retained on 10.0 mm sieve. Weight the empty cylindrical measure. Let the weight be ‘a’ grams. Fill the aggregate in the cylindrical measure in three layers, tamping each layer 25 times with the rounded end of the tamping rod.

ContactThe crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100 Lab Report

ContactAggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample= Aggregate Crushing Values for Roads and Pavement Construction

ContactThe aggregate crushing value test is an important test of aggregates. It gives a numerical index of the strength of the aggregate and it is used for concrete in

ContactThe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing apply a gradually increasing compressive load. The strength of aggregate is calculated by the crushing value test. The aggregates used should be strong enough to with stand the stresses which comes on to it.

ContactThe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. 2.Apparatus Required Fig. 1: Balance

ContactSep 15, 2014It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft.
