Concrete Cure Times Chart . A common example is walking on the slab without leaving footprints. But to answer the question of, “how long does concrete take to set?” concrete setting time is generally 24 to 48 hours.
Effect Of Curing Time On Compressive Strength Of Geopolymer Concrete... | Download Scientific Diagram from www.researchgate.net
Without proper curing the, 4000 psi concrete may not reach 2000 psi in 28 days. For most concrete structures, the curing period at temperatures above 5º c (40º f) should be a minimum of 7 days or until 70% of the specified compressive or flexural strength is attained. Pond curing uses berms or other containment around the pour to hold 4” to 12” of water on top of the concrete.
