Sand is one of the important constituents of concrete. The main purpose of mixing sand (fine aggregate) in concrete is to fill the voids between Coarse aggregate. And the voids between fine aggregate is filled with cement. Sand bulks the concrete and helps to increase the workability of concrete.
Sand is formed by the weathering of rocks. Well, different regions use the variety of sands (Pit sand, River sand, Sea Sand) in construction according to the availability. A good fine aggregate should be well graded (all particles that have almost same size).
The fine aggregate used for construction should pass 4.75mm sieve and retain on 150microns sieve.
Below mentioned tests are the simple tests which you can perform quickly on site to find out the quality of Sand. These tests include checking the properties of Sand which affect the strength and the quality
