All You Need to Do Know About Ready-Mix Concrete Curing

The first phase of curing needs to be implemented when the ready-mix concrete is first placed for the slab. The operators must check the evaporation rates and keep an eye if the bleed water is evaporating the surface faster than it is rising out of the concrete to avoid plastic shrinkage.

You can sustain the curing process by maintaining the moist condition of newly placed concrete by moist curing. The usual duration for moist curing is seven days, but the longer the concrete is cured, the better. There are several methods for moist curing, but the most common are continuous spraying/fogging or a

Concrete Curing: Do's And Don'ts to Prevent Cracks and Shrinks

Moist curing is a common method of concrete curing. It involves wetting the concrete slab often with water (5-7 times per day) for the first 7 days. This method ensures your concrete slab will be extremely strong and durable, because it allows the moisture to evaporate slowly, preventing cracks and shrinks.

Techniques - Cement & Concrete Tutorials

Concrete curing time can be sped up by curing it in warmer temperatures and with more air flow. Keep in mind that you do risk cracking if you do this. If the concrete starts curing too quickly due to drying out from heat, air flow and low humidity then it can make the concrete contract too much and cause cracking.
