Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined

18/07/2021 Determine the aggregate crushing value of coarse aggregate 2. Check the suitability of coarse aggregates to use in different types of road. Apparatus Required for Crushing value test. 1. A balance should be accurate up to 1 gm 2. IS sieves of size 12.5 mm, 10 mm, and 2.36 mm 3. Mould, measuring cylinder with plunger and base plate 4. A compression testing machine. 5. Dial gauge.

2.16 The aggregate crushing value is the ratio of the mass of fines formed by the crushing process to the total mass of the sample expressed as a percentage. Percentage fines = B/A x 100 (to the first decimal place) where . A = The mass of the surface dry sample. B =The mass of the fraction passing the 2.36mm sieve after crushing. 2.17 The mean result of the two tests will be reported to the

Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample.

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. 2.Apparatus Required Fig. 1: Balance Balance should be accurate upto 1 gm.

17/05/2019 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

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 The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) 1963 consists of: 1) A

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

Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100.

30/03/2020 The aggregate crushing value test evaluates the ability of the aggregates used in road or pavement construction to withstand the stresses induced by moving vehicles in the form of crushing. With this, the aggregates should also provide sufficient resistance to crushing under the roller during construction work and under rigid tyre rims of heavily loaded animals or men

Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember . It is recommended that the crushing value of aggregate should be less than 30%. If it is more
