concrete aggregate (RCA) is nothing more than PCC crushed into aggregate-sized particles. These particles consist of the original aggregate particles and the adhered mortar (5). At least 36
Overview RYAN Aggregate is a collective term for the mineral materials such as sand, gravel, and crushed stone that are used with a binding medium (such as water, bitumen, Portland cement, lime, etc.) to form compound materials (such as bituminous concrete and Portland cement concrete).
Procedure: Compressive Strength Test of Concrete Cubes For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15cm x 15cm x 15cm are commonly used.

BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load.The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.

The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load. Lower the aggregate crushing value greater will be the "resistance to crushing under gradually applied compressive load".
aggregate crushing value This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm
Recycled aggregates are obtained by crushing concrete elements, in the same way that natural aggregates are produced by crushing stone taken from quarries. However recycled aggregates have some different properties that need to be accounted for when producing recycled aggregates concrete.

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.
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.
