W A is Dry weight of aggregate The weight in g of ovendried aggregate in air W B is Weight of aggregate immersed in water The weight in g of the saturated surkedry aggregate in air Note Water absorption shall not be more than 2 per unit by weight. In case in Water absorption is higher than 2 than soundness test is required
Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test. Exp 4
The aggregate crushing value ACV of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An
2020-6-30Exp 4 Aggregate Impact Value Civil Engineers Pk. Aggregate Impact Values AIVs below 10 are regarded as strong and AIVs above 35 would normally be regarded as too weak for use in road surfaces Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar and indicate similar aggregate strength properties Aggregate Impact Value Test Specifications

Aggregate Crushing Value Test Procedure and Result Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be determined and used instead
Apparatus Of Aggregate Crushing Value Test. Aggregate crushing value. Aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is 2386 part iv 1963 the apparatus used is cylindrical measure and plunger, compression testing machine, is sieves of sies 125mm, 10mm and 2
Impact Test on Aggregates. Impact value of aggregate will give aggregate capability against sudden loads or forces. For this test also aggregate passing through 12.5mm and retained on 10mm sieve is taken and oven dried. Fill the cylinder with aggregate in 3 layers, 25 strokes of tamping for each layer. Weight w1 noted. Get Price
