How Concrete is Made Portland Cement Association

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

What Is Bulking Of Sand? And Its Importance [Civil Planets]

2021-10-22  If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. For Example, If we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3. The reason for that is the moisture content present in the sand makes it a little bulkier.
