Abstract
An improved freeze-thaw durability cementitious composition is provided that uses at least partially degradable polymeric particles that are blended directly into the cementitious composition mixture. The degradable polymeric particles provide void spaces in the cementitious material matrix, and such void spaces act to increase freeze-thaw durability of the cementitious material.
