Concrete Production Process marstllaroilconcrete

Jul 26, 2016  Typical recommendations for curing concrete are to allow it to set for seven days for mixes that contain only Portland cement, and for 14 days if the concrete contains admixtures. The specific length of time concrete needs to cure is affected by the outdoor temperature, the concrete mixture and the specific strength of the concrete.

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.
