摘要：
A method of delivering an admixture providing freeze-thaw resistance to a cementitious composition is provided which includes the addition of a viscosity modifying admixture containing at least one of polymeric microspheres, at least partially degradable polymeric particles, or gas generating additives to cementitious compositions. The polymeric microspheres, at least partially degradable polymeric particles, and gas generating additives provide void spaces in the material matrix, and such void spaces act to increase freeze-thaw durability of the material.
