Patent abstract
An improved freeze-thaw durability dry cast cementitious composition is provided that uses very small (0.1 μm to 100 μm average diameter) polymeric microspheres that are blended directly into the mixture and optionally gas-generating additives. The polymeric microspheres provide void spaces in the material matrix that act to increase freeze-thaw durability of the material. In this dry cast cementitious composition, polymeric microspheres act as pre-formed voids.
