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.
Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.
Crushing old concrete to make aggregate for new concrete is increasing in popularity for several reasons. • Owners want projects to be sustainable and LEED certified. Recycled concrete qualifies for recycled material credits, and because it usually is found locally, it qualifies for local credits.
The determination of aggregate crushing strength is an important test in your civil engineering know that aggregates are the one the basic unit of building are used in several construction processes such as in concrete, road construction etc..

Home / Building Technology Guide / Building Materials / Los Angeles Abrasion Test on Aggregates Values for Pavements and Roads Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration.
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.

coarse aggregate and more volume of coconut shell will be required to replace equal weight of coarse aggregate in concrete. The bulk density of coconut shell obtained is 648 which far less thanis about 1437 of coarse aggregate implying its good for lightweight concrete. The aggregate crushing value of
01. Crushing Test on Aggregate. The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate.
The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.

Comp. strength (concrete) < Comp. strength (aggregate) • The crushing strength of aggregate cannot be tested with any direct test. There are some indirect tests to inform us about the crushing strength of aggregate. –Test method: Crushing value test Other Mechanical Properties of Aggregates:
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS
