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.
The concrete with an increased volume of artificial aggregates exhibited decrement in strength but satisfied the code requirements to use it as structural construction material. The study concludes that artificial aggregates may efficiently replace natural coarse aggregate in the production of structural concrete, bringing numerous advantages ...
