AGGREGATE CRUSHING STRENGTH TEST Theory and Scope: This is one of the major Mechanical properties required in a road stone. The test evaluates the ability of the Aggregates used in road construction to withstand the stresses induced by moving vehicles in the form of crushing.

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:

Crushed concrete aggregate (CCA) is made from unused, returned concrete, and old demolished concrete that is clean enough to be used for new concrete mixes. Crushing old concrete to make aggregate for new concrete is growing in popularity for many reasons the with first being able to create a more sustainable or "green" concrete.

Similarly aggregates used in Portland cement concrete mixes must be clean and free from deleterious substances such as clay lumps, chert, silt and other organic impurities. Aggregate tests In order to decide the suitability of the aggregate for use in pavement construction, following tests are carried out: Crushing test Abrasion test Impact test

The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.

Abstract: This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test.

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.
