How long should you keep concrete wet after pouring?
Then, how soon should I water concrete after pouring?
Read about properly curing concrete slabs. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab. The enclosed area is continually flooded with water. Ideally, the slab could be water cured for 7 days.
Moreover, should concrete be kept wet while curing?
ANSWER: Keeping concrete moist helps the curing process. Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries. Moist-curing concrete for 20 days more than doubles its strength compared to four days of moist-curing, which is considered a minimum.
Heavy rain can cause problems to freshly poured concrete as it can wash out some of the cement from the mix. This can weaken the surface of the concrete, making it a softer consistency and decreasing the strength of the concrete.
