- Guidelines for Selecting Good Sand That can Be used for Construction.
Sand Should have to following main properties to be treated as good for construction use: Silt Content should be less than 3% by weight (12% by volume in 10 min) Sand should be free from Organic materials. - Requirements of good quality sand
For brickwork, fine sand used must not have a modulus less than 1.2 to 1.5, and the slit preferred is generally 4 percent.
Concreting works require coarse sand with a modulus of 2.5 to 3.5 and the slit content must not be less than 4 percent.
