· Sand should be wellgraded and free from the slit or any organic matter. Of the total material cost, the sand contribution is up to 12%. Around cubic ft per sqft that makes a total of 1800 cubic ft for 1000 sqft. Aggregates . Coarse aggregates are generally used for making concrete mixing with sand, cement and water.
· Though water makes cement easier to pour and helps it to harden, cement and water by themselves don't hold together very well. The addition of sand makes cement more binding. Cement mixed with water and sand becomes mortar, the paste used to hold bricks together. Once you add gravel to the mix, it becomes concrete.
