Take test samples of aggregates 2019-5-17 Take the aggregate out of the cylinder and sieve them through a 2.36 mm IS sieve. Weight this fraction passing through it to an accuracy of 0.1 gm. 2017-5-29 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. APPARATUS 2000-2-7 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 2018-4-26 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. Aggregate crushing value= ( W2 / W1 ) × 100 2021-6-4 Aggregate Crushing Value Test Procedure and Result. The procedure of Aggregate Crushing Value Test Take the Empty weight of cylindrical measure as W1 Fill aggregate sample passing through 125 mm and retained on 10 mm IS sieve in measuring cylinder in 3 equal layers such that each layer is Find out the weight of aggregate sample W W2 W1 2021-12-28 Test Procedure. The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped Aggregate Crushing Value Test Procedure And Result. 03/10/2019 Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height. 2021-7-2 The load shall be released and the whole of the material removed from the cylinder and sieved on a 2.36mm IS sieve. The fraction retained on the sieve shall be weighed. Repeat the whole procedure for another set. The aggregate Aggregate Crushing Value Test INTRODUCTION Procedure The aggregate passing 12.5 mm IS sieYF and retained on10 mm IS sjeySiis selected for standard test. The aggregate should be in surface-dry condition before testing. The aggregate may be dried by heating at a temperature lOO:>Cto llO°C for a period of 4 hours and is tested after being 2021-12-1 The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386 (Part 4):1963) 2019-3-11 AGGREGATE CRUSHING VALUE 1.Objective The 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. 2018-4-26 Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength. AGGREGATES CRUSHING VALUE TEST (IS: 2386 PART-IV) Purpose: Purpose of this test covers the procedure to determine the aggregates crushing value of coarse aggregates. Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 2000-2-7 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 2021-6-4 Aggregate Crushing Value Test Procedure and Result.
