subjected to a standard loading regime applied through the plunger. This action crushes the aggregate to a degree which is dependent on the aggregate’s crushing resistance. This degree is assessed by a sieving test on the crushed specimen and is taken as the Aggregate Crushing Value. 7.7.1.4 Sampling.

• ### How to Determine the Aggregate Crushing Strength Value

Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.

• ### Crushing value apparatus (ACV), Aggregates testing

The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure. Cylinder, plunger and base plate are made from special alloy steel, hardened to 650 HV (57,8 HRC), and

• ### aggregate crushing standard brianzamotostoriche.it

Aggregate Crushing Value according to IS 2386 (Part iv)-1963 aggregate crushing value is designed for only for IS Sieves of sizes 125mm, 10mm and 236mm, for 20mm and 10mm coarse aggregate we need to take different ranges of sieves, then cylinders size will also changes.

• ### standard crushing value of aggregate

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
