Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.Crushing value of aggregates indicates its strength.Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

More DetailsAggregate impact value civil engineering.The apparatus used for determining aggregate impact value of coarse aggregates is impact testing machine conforming to is 2386 part iv- 1963,is sieves of sizes 12.5mm, 10mm and 2.36mm, a cylindrical metal measure of 75mm dia.And 50mm depth, a tamping rod of 10mm circular cross section and 230mm length, rounded at one end and oven.
More DetailsAggregate crushing value the aggregate crushing value indicates the ability of an aggregate to resist crushing the lower the figure the stronger the aggregate, i.E.The greater its ability to resist crushing the aggregate passing 12.5 mm sieve and retained on 10 mm sieve is selected for standard test compression testing machine with.
More DetailsThe 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.See also.Basic units and measurements for civil engineers.Different types of cement.
More DetailsThe 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 12.5 mm sieves and retained 10 mm sieves are filled.
More DetailsThis test is very similar to aggregate crushing test in which a standard force 400kn is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.Granular sub-base is subjected to repeated loadings from truck types.The stress level at the contact points of aggregate particles is quite high.
