When cement reacts with water it undergoes two major reactions. One reaction is the formation of calcium hydroxide compounds which are porous, unstable and are easily susceptible to aggressive water and chemical attack. Calcium hydroxide can amount to as much as 25% of the cement, by volume.

The unique blend of pozzolans in the Universal White Cement™ react with the calcium hydroxide and turn it into a fibrous cluster like network forming a dense cement matrix. The improved water tightness reduces the amount of water and chemicals that can infiltrate the cement matrix and cause it's early deterioration and breakdown.

Reducing the amount of calcium hydroxide is the key to a stronger and longer lasting cement.
