Figure 6 depicts the variation in the crushing values of the POC aggregates from various states in Malaysia. As POC aggregate is very much porous and lighter in nature, the load bearing capacity may be significantly affected. The highly porous nature of the POC aggregate will induce crack propagation much easier than dense cement paste.

Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.

IMPACT CRUSHING. Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.

The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides are lative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact.
