What is the Right Water-Cement Ratio for Mix Design?

Oct 21, 2011  The practical range of water-cement ratio ranges from 0.3 to 0.8 that gives stiff and weak concrete respectively. Weak concrete means a fairly wet concrete. A compressive strength about 5600psi can be obtained from a concrete of water-cement ratio 0.4. This value will go down to 2000psi if a water-cement ratio of 0.8 is used.

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.
