Abstract
An improved freeze-thaw durability wet cast cementitious composition is provided that uses in-situ production of gas by gas generating additives and optionally polymeric microspheres that are blended directly into the mixture. The gas generating additives and the polymeric microspheres provide void spaces in the material matrix, and such void spaces act to increase freeze-thaw durability of the material.
