How long should concrete cure before building a house?
Seven to 28 days According to Concrete Network, concrete should be allowed to cure for at least seven days before it’s built on. However, waiting longer will greatly reduce the risk of the concrete cracking. Concrete continues to cure up to 28 days after it is poured, at which point it reaches maximum strength.
How soon after pouring concrete can you build on it?
You can start framing on a poured concrete slab about seven days after it’s poured. At this point, a concrete slab will have 70% of its fully cured strength. Poured concrete can take up to 28 days to fully cure.

Although the bulk of the hydration process takes place in the hours and days immediately after the pour, concrete needs 28 days to fully dry. While the slab will harden and lighten in color before 28 days, don’t be fooled into thinking it’s done hydrating.

How long should it take concrete to fully cure?
The longer you allow concrete to cure, the harder it becomes. While you may only need to keep the concrete protected for the first week while it cures, it actually takes it about 28 days to reach its full strength and hardness. After the concrete is poured and floated, the curing process ensures it hardens properly.
When do we have to start and stop curing concrete?
The Normal final setting time of cement is six to eight hours. In short, the curing should start after minimum six hours (Final setting time of cement) and not less than 24 hours. Thus, when concrete curing has to start is varies and depends on when the surface of the concrete begins to dry.
When to start curing of concrete?
The right time of curing of concrete depends on: Initial Curing When the concrete is placed and compacted, bleeding of water occurs and rises through the surface of concrete due to the settlement of concrete. Intermediate Curing Intermediate curing is done when the concrete surface finishing operations have been carried out before the final set of concrete. Final Curing
