Abstract:
A method for improving air entrainment comprising the steps of: providing a compound selected from an amphoteric, an alkyl polyglycoside, an ester, a triglyceride, a triglyceride derivative, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof; dispersing the compound on a finely particulate carrier to form a treated carrier; and adding the treated carrier to a cementitious mixture is provided. A composition for improving air entrainment, including a compound selected from an amphoteric, an alkyl polyglycoside, an ester, a triglyceride, a triglyceride derivative, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof, wherein the compound is dispersed on an organic particulate carrier and added to a cementitious mixture, is also provided. The composition may be incorporated into a concrete structure.
