PROVIDING FREEZING AND THAWING RESISTANCE TO CEMENTITIOUS COMPOSITIONS

摘要

An improved freeze-thaw durability wet cast cementitious composition is provided that uses microspheres that are blended directly into the wet cast cementitious composition. The microspheres provide voids in the wet cast cementitious composition material matrix, and such voids acts to increase freeze-thaw durability of the cured and hardened cementitious material.
