This method uses saturate steam at pressure ranging from 125-150 psi and temperature of 178℃, this method usually requires additional equipment such a

Steam curing at atmospheric at temperature of 65℃ in a curing chamber accelerates the hardening process.

In countries where the climate is favorable, green blocks are moist cured at normal temperature of 20℃to 37℃(as in the south of China), this type of c

Sufficient curing time should always be allowed for concrete to develop adequate strength before it is loaded.

Curing methods that use water, such as sprinkling, ponding, and using wet coverings, are the most effective means and should be used when​ever practic
