Aggregate passing through sieve and retained on 10mm sieve is taken. About kg material is taken. The aggregate in a surface dry condition is filled into the standard cylindrical measure in three layers ...
The test is used to assess the quality of fine aggregate used in concrete and asphalt. 05. ACV (Aggregate Crushing Value) and 10% FACT (Fines Aggregate Crushing Test) The test results are used for quality control, by means of particle strength, of aggregate for concrete, surfacing (chips) and asphalt, as well as crushed stone base.
Oct 25, 2019 · An aggregate for cement concrete flooring mix must conform to the requirements of IS: . The aggregate crushing value, when determined in accordance with IS: 2386 ( Part IV)196311 shall not exceed 30 percent. Coarse aggregate – The grading of graded coarse aggregate for cement concrete flooring mix shall be within the limits.
Dec 19, 2019 · If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
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 sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (WaWe) W2= Weigh of aggregates passing through IS sieve.
The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 1). Dry aggregates passing through mm sieves and retained 10 mm sieves are filled ...

Mar 30, 2020 · Procedure of Aggregate Crushing Value Test:. Sieve the test material through mm and mm IS sieve. Take test samples of aggregates passing through mm IS sieve and retained on 10 mm IS sieve (minimum 3 Kg). Dry theme in an oven for 4 hours at a temperature of 100 °C to 110 °C and then cool at room temperature.
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 –, 10mm and Procedure to determine Aggregate Crushing Value i) The aggregates passing through [.]
The LA value was estimated with the help of some aggregate tests (rock impact hardnessRIHN, coefficient of rock strengthCRS and aggregate crushing value .
The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact.
