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 average compressive strength of concrete was 28.46 N/mm2, when 60 percent natural sand, 35 percent of the artificial sand and 5 percent plastic waste were used in concrete. It therefore concludes that 5 percent plastic waste and 35 percent artificial sand replacement is possible good proportion in concrete without affecting the strength of mix.
1.1 These test methods cover the chemical analysis of glass sands. They are useful for either high-silica sands (99 % + silica (SiO 2 )) or for high-alumina sands containing as much as 12 to 13 % alumina (Al 2 O 3 ). Generally nonclassical, these test methods are rapid and accurate. They include the determination of silica and of total R 2 …

and one of the major materials is quarry stone dust (Artificial/Robo/M -SAND). Using different proportion of this robo sand along with sand the required concrete mix can be obtained. Replacement of natural fine aggregate is done with artificial fine aggregate by 20%, 40% 60% and also the compressive Strength of that concrete cube is found. This ...

Natural (River) Sand. Natural sand has an excellent modulus of 2.78 and, after washing in clean water, complies with Zone II according to IS: 383-1970. The specific gravity of this natural sand was found to be 2.55. The water absorption and moisture values obtained for the sand used were 6% and 1.0%, respectively. 3.
