How many days required for concrete curing?

Answer 1

That depends on the concrete, as well as weather conditions, and the load the concrete would be subjected to. Concrete gains strength over time and the usual benchmarks are 7 days, and 28 days. At 28 days concrete has usually cured to nearly its maximum strength. For a concrete footing in a residential environment say a deck or home the concrete will usually cure for a minimum of three days before the formwork is removed and the rest of the structure is built. For a commercial or civil project the curing is subject to the engineers discretion.

self compacted concrete
