  • Aggregates for Concrete

    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.

  • Pavement materials: Aggregates

    Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 partIV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
