Curing Blanket

Summary

Curing Blanket - A blanket is an insulative layer used to retain heat and moisture in concrete during curing.

Technical Information

It is important to regulate the curing conditions of a concrete slab. Failure to do so can lead to serious structural and aesthetic problems in the long run. A blanket is a vital tool with which good curing can be achieved. Either waterproof or permeable blankets can be used, depending on the requirements of the situation.

Using blankets can:

Reduce the risk of thermal cracking or curling in cold weather as they reduce the temperature gradient in the slab by reducing heat loss from the surface.
Reduce the risk of plastic shrinkage as they reduce the rate at which moisture is lost from the surface.
Increase the rate of strength gain in the concrete in cold weather as they maintain a higher temperature within the concrete, causing hydration to happen more quickly.
