Concrete Guidelines – Dmireadymix

Effective curing is absolutely essential for surface durability. Fresh concrete must be kept warm and moist until the mixing water combines chemically with the cement (hydration). Without curing, the strength of the concrete (where it is needed the most) is basically reduced in half. A 4000 PSI mix becomes a 2000 PSI mix at the surface with no
