Curing is the protection of fresh concrete from evaporation and temperature extremes which might adversely affect cement hydration. If concrete is to gain potential strength and durability it must have sufficient water for the hydration of the cement, and a temperature conducive to maintain this chemical reaction at a rapid, continuous rate.
Oct 04, 2019· Cement additives, including cement dyes, are all designed to make working with cement easier and produce far better results. When used in such mixes, cement is not always a perfect product. It can shrink during drying out causing cracks to develop, and it can be too rigid.

Aug 23, 2019· The process of curing concrete becomes more challenging in cold weather since, to properly set and reach maximum strength, fresh concrete must be protected from freezing for at least the first 24 hours, or until it reaches a minimum strength of 500 pounds per square inch (psi). Concrete that freezes at an early age can lose much of its overall strength.
