Aggregate Crushing Value and Its Test Procedure: One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS: 2386 partIV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through and retained on ...
Concept and significance of the Aggregate crushing value test. 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 ...
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 surfacedry sample
BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive method is applicable to aggregates passing a mm test sieve and retained on a mm test sieve.
The aggregate impact value should not exceed 45% by weight of the aggregate for concrete other than wearing surface.

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 ...
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 result may be anomalous, and in
Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The " aggregate crushing value " give a relative measure of the resistance of
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 mm IS Sieve divided by weight of aggregate sample taken for test" Aggregate crushing value = (W3 / W) or W3 / (W2 – W1)
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
