Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling aggregate should be much smaller than the finished item but have a wide variety of sizes.

Aggregate Crushing Value Civil Engineering according to IS 2386 (Part iv)1963 aggregate crushing value is designed for only for IS Sieves of sizes 125mm 10mm and 236mm for 20mm and 10mm coarse aggregate we need to take different ranges of sieves then cylinders size will also changes

aggregates with typical range values are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4) sieve and predominantly retained on the 75 181m (No. 200) sieve is called fine aggregate or sand and larger aggregate is called coarse aggregate.
