The determination of aggregate crushing strength is an important test in your civil engineering labYou know that aggregates are the one the basic unit of building materialsAggregates are used in several construction processes such as in concrete, road.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.Number. Report the mean as the aggregate crushing value, unless the individual results differ by than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value.Jul 18, 2021 A lower crushing value indicates a lower crushing fraction under a specific load and would give a better result, longer service life and economic performance. Aggregate crushing value test codes. Following are the standard guidelines for the crushing value test on the aggregates • IS 2386 (Part 4) 1963 • BS 812–110 1990. Objective. The.
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing apply a gradually increasing compressive load. The strength of aggregate is calculated by the crushing value test. The aggregates used should be strong enough to with stand the stresses which comes on to it. Aggregate are the important part of.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.The method of test covers the procedure for determining the aggregate impact value of coarse aggregates.
