Effect of use of Silica Sand as Fine Material in Concrete

2015-6-25  Silica sand is obtained from the raw material (locally available in mamuara village in Kutch district). After washing the raw material the silica sand is separated by sieve size 1.18 of raw material. Raw material is washed for taking out the clay material which is useful in making the tiles. In the raw material about 10% is clay which is supplied to the ceramic factories. From the raw material different size of silica sand are separated by different size of sieve. Sand size of 30 mesh to 80 mesh (500 micron) is used in the Limestone industries. Sand size 1.18mm to 600 micron can be used in making concrete mix as the partial replacement of fine aggregate. Nearly about 200 tones of silica sand is obtained daily after washing the raw material.

In order for the filter to be effective, each grain of sand must be roughly the same size, generally 0.4 to 0.6 millimeters. The most common sand filter media is 20-grade silica, which creates a mesh so tight it can sieve particles as small as 20 microns. Cons: Sand can clump, calcify and create channels where water slips through unfiltered.
