05/05/2010· 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.

The specified limits of pe cent aggregate crushing value N ote:- For strong aggregate, crushing value should be low. For surface courses this value should not exceed more than 30%

More### Aggregate Crushing Value Test Procedure And Result

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 applied through a plunger in a compression testing machine.

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 i) The aggregates passing through 12.5mm and retained on

Crushing strength of road stone may be determine either on aggregates or on cylindrical specimen cut out of rocks. The two tests are quite different not only in the approach but also in the expression of the results. Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is

The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the ﬂexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality. Normal values for ACV range from 14 to 30%, and for 10% FACT from 100kN to 300kN. There is
