Aggregate Crushing Value Test -Determine Aggregate
Apr 26, 2018· 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. Aggregate crushing value=( W2 / W1 ) × 100
Aggregate crushing = (W2/W1)*100 Value (per cent) Aggregate Crushing Mean Value =
May 05, 2010· Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W =Weight of surface dry sample.
DETERMINATION OF AGGREGATE CRUSHING VALUE AIM This method of test covers the procedure for determining the aggregate crushing value of coarse aggregate. THEORY The aggregate crushing value gives a relative measure of the resistance of aggregate in bulk to crushing under a gradually applied compressive load.
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 sizes 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing Value.
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 aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate
1SCOPE. The ACV of an aggregate as defined hereunder is determined by crushing a prepared confined aggregate sample under a specified, gradually applied compressive load and determining the percentage of the material crushed finer than a specified size. Definition. The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is

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.
Scope: This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
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 open-ended steel cylinder of 150 mm nominal
DETERMINATION OF AGGREGATE CRUSHING VALUE. The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in

Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration.

This British Standard, a part of the BS 812 series, describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
THE DETERMINATION OF THE 10 PER CENT FINES AGGREGATE CRUSHING VALUE 1 SCOPE The 10 per cent Fines Aggregate Crushing Value (10 % FACT) as defined hereunder is determined by measuring the load required to crush a prepared aggregate sample to give 10 per cent material passing a specified sieve after crushing. The procedure described in SABS
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. Chat Online.
The specimen is then subjected to a standard loading regime applied through the plunger. This action crushes the aggregate to a degree which is dependent on the aggregates crushing resistance. This degree is assessed by a sieving test on the crushed specimen
June 29, 1990. Testing aggregates - Part 110: Methods for determination of aggregate crushing value (ACV) Method for aggregates passing a 14.0 mm test sieve and returned on a 10.0 mm test sieve. Also describes a method for other size fractions.
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
