· Our sand calculator is a tool designed specifically to help you with calculations you may do on the building site, or when you are doing a bit of home improvement. Estimating the required amount of any building material is a difficult task, and errors may result in either the material running out when the project is in full swing, or in heaps of sand lying around after the earthwork is completed.
· Thus, silica sand is the form of quartz which has been broken down into tiny granules. Most of the time, these tiny granules are found in nontropical regions of the world which are collected and processed into the silica sand of different grades and different sizes. The silica sand has different uses in various industries as briefed below:
Fine sand – to mm; The properties of fine sand can be associated with river sand, which, as the name suggests, are obtained from river banks. It is usually whitishgray in color and is mostly used in plastering. The artificial sand or M sand can also be an alternative to river sand. Medium sand – .

It does content very high silt fine particles (as in case of Filter sand). Presence of other impurities such as coal, bones, shells, mica and silt etc makes it inferior for the use in cement concrete.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at billion to billion tonnes a year for 2012 alone.
