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.
Claims17
A cementitious freeze-thaw damage resistant composition comprising hydraulic cement, and polymeric particles at least partially degradable by the cementitious composition environment, wherein the degradable polymeric particles have an average diameter of about 10 μm or less.
A method for preparing a freeze-thaw damage resistant cementitious composition comprising forming a mixture of water, hydraulic cement, and polymeric particles at least partially degradable by the cementifious composition environment, wherein the degradable polymeric particles have an average diameter of about 10 μm or less.
