Freshly placed concrete needs more than time to gain strength. Curing is the management of moisture and temperature so the cementitious materials can hydrate and the concrete can develop its intended properties. It is not simply a process of letting the slab dry. Original editorial graphic, not a photograph of an actual project. 1. What does concrete curing mean? When cementitious materials react with water, hydration products form and the concrete develops strength and other properties. Early moisture loss can interrupt that process near the surface. Large or rapid temperature changes can also increase the risk of early-age distress. Good curing practices address both concerns, within the requirements of the project specification. Figure 1.
