· The aggregate crushing value should not be more than 45% by weight. For aggregates used for concrete other than wearing surfaces and 30% by weight for concrete to be used as wearing surfaces such as runways, roads, and airfield pavements. …
Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.
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.
Crushing Value Of Aggregates - reiseburobulent de. As per the definition given in the IS 2386 Part III 1963 Indian Standard- Methods of Test for Aggregates for Concrete Specific Gravity Density Voids Absorption and Bulking the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural .
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 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on .
· 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 aggregate crushing value should not be more than 45% by weight. For aggregates used for concrete other than wearing surfaces and 30% by weight for concrete to be used as wearing surfaces such as runways, roads, and airfield pavements. …
· The aggregate crushing value should not be more than 45% for aggregate used for concrete other than the wearing surfaces. 30% for concrete used the surfaces such as runway, roads and air field pavements. References: Aggregate Crushing Value; Aggregate crushing value test
The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface. This test must be done before it comes to road and pavement construction. Calculation Table for aggregate crushing value …
crushing strength of course aggrgate for concret. Mar 11, 2019· The aggregate crushing value of the coarse aggregates used for cement concrete pavement at surface should not exceed 30% and aggregates used for concrete other than for wearing surfaces, shall not exceed 45% as specified by Indian Standard (IS) and Indian Road Congress (IRC).

· Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.
For the preparation of economical concrete mix on should use largest coarse aggregates feasible for the structure. IS-456 suggests following recommendation to decide the maximum size of coarse aggregate to be used in P.C.C & R.C.C mix. . The aggregates crushing value gives a relative measure of resistance of an aggregate to crushing 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 surface-dry sample
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.

This study investigates the effect of aggregate size on the compressive strength of concrete. Two nominal mixes, that is, 1:2:4 and 1:3:6 were used in the study.
Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture. It is reported […]
