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 …

IS 2386

The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like runways and roadways. Discussion: 1.

Aggregate is a granular material obtained by processing natural materials.BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as sand.Aggregate consists of particles of a rock, of a controlled particle size distribution, used in the construction of a building or civil engineering structure.

Compression test on concrete

Aug 27, 2019· The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the type of road construction.
