8 Truths about Concrete Moisture - Concrete Moisture

Since most concrete floors have a vapor retarder below them, this moisture must move upwards in order to escape. The significant movement of water within the slab means that the moisture condition will vary by depth. Generally, the surface of the slab is drier, while deeper in the concrete, the moisture concentration is higher.

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.
