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.

The Aggregate Crushing Value (ACV) Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. All parts of the apparatus are powder coated or galvanized steel, heat treated and ground ...

3 2 Wet test 3.2.1 Preparation of the test sample The same as in 3.1.1. 3.2.2 Filling the cylinder Proceed as in 3.1.2. When the mass of the aggregate has been determined, the aggregate is immersed in water for 24 h. After soaking, take the aggregate out, allow to drain for 5 minutes, and then surface-dry it by rolling it in a damp cloth.

Aggregate Crushing Value Test - Procedure And . Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve. The aggregate sample is filled in a cylindrical mold and a load of 40 ton is ...

Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample

Procedure of Aggregate Crushing Value Test Put the cylinder in position on the base plate and weigh it (W) . Put the sample in 3 layers, each layer being subjected to 25 strokes using the tamping rod.

2.1 Object - This method of test covers the procedure for determining aggregate crushing value of coarse aggregate. NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of 'aggregate crushing value' 30 or higher, the ...

When the mass of the aggregate has been determined, the aggregate is immersed in water for 24 h. After soaking, take the aggregate out, allow to drain for 5 minutes, and then surface-dry it by rolling it in a damp cloth.

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.

Note 1: A procedure for testing coarse aggregate larger than 19.0 mm [3 / 4 in.] is covered in Test Method C535. Thus coarse aggregates with a maximum size between 19 mm [3 / 4 in.] and 37.5 mm [1 1 / 2 in.] may be tested by Test Method C535 or Test Method C131/C131M.

Calculation of Aggregate Crushing Value: Aggregate crushing value can be found by the following formula, "Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test" Aggregate crushing value = (W3 / W) or W3 / (W2 – W1)

Jan 04, 2014· Procedure of testing Aggregate Crushing Value (ACV): 1. Make a sieve analysis and get sufficient amount of aggregate by using 14.0 mm passing sieve and 10.00 mm retained sieve. 2. After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm. 3.

3.Reference IS 2386(Part 4):1963 Methods of Test for Aggregates for Concrete- Mechanical Properties. Reaffirmed-Dec 2016 4.Procedure 1.The material for the standard test shall consist of aggregate passing a 12.5 mm IS Sieve and retained on a 10 mm IS Sieve, and shall be thoroughly separated on these sieves before testing.

Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod.
