Briefly explain the aggregate crushing value test procedure. What is the specified standard size of aggregates? How is the aggregate crushing value of nonstandard size aggregate evaluated ? Aggregate crushing value of material A is 40 and that of B is 25. Which one is better ~nd why? What are the applications of aggregate crushing test?
The aggregate impact value should not exceed 30% by weight for concrete wearing surface such as runways, roads, pavements, floors etc. IS:, IS: 2386 (Part4).

The aggregate impact value should not exceed 45% by weight for aggregates used for concrete other than for wearing surfaces and 30% by weight for concrete for wearing surfaces, such as runways, roads and pavements, as per IS : 383 – 1970
of 20 mm and satisfying the grading requirements of BIS (IS: ) is used in both normal and recycled aggregate concretes. The specific gravity of coarse aggregate is and the fineness modulus of the crushing value of the coarse aggregate used as %, the
13 AGGREGATE CRUSHING VALUE: The aggregate crushing value gives a relative measure of resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing strength value is useful factor to know the behavior of aggregates when subjected to wear.
Tests were conducted to determine the properties of plastic aggregate such as density, specific gravity and aggregate crushing value. As 100% replacement of natural coarse aggregate (NCA) with plastic coarse aggregate (PCA) is not feasible, partial replacement at various percentage were examined [8], [9].
Fine aggregate of Zone II as per IS: is generally suitable for pumped concrete provided 15 to 30% sand should pass the 300 micron sieve and 5 to 10 percent should pass the 150 micron sieve. Fine aggregate of grading as given in Table 2 is best for pumped concrete.
