What is the Difference Between Concrete and Cement?

 · Cement does not dry, it hydrates. The process of making the cement bakes all of the water of hydration out of the crystalline structure of the components. When water is added it rehydrates the this crystalline structure that is what allows the cement or concrete to harden or cure. This is why cement can cure under water.

Tips for Curing Concrete in Cold Weather

 · 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.
