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;
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.

1. A method for improving air entrainment, comprising the steps of: providing a compound selected from the group consisting of: an amphoteric, an alkyl polyglycoside, an ester, an ethoxylated triglyceride, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mi
1. A method for improving air entrainment, comprising the steps of: providing a compound selected from the group consisting of: an amphoteric, an alkyl polyglycoside, an ester, an ethoxylated triglyceride, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof;dispersing separately the compound on a particulate carrier comprising limestone to form a treated carrier; andadding the treated carrier to a cementitious mixture. 2. The method according to claim 1, wherein the cementitious mixture includes Portland cement. 3. The method according to claim 1, wherein the cementitious mixture includes an air entrainment agent that is different from the compound. 4. The method according to claim 1, wherein the compound is used in an amount ranging from about 0.01% to about 10% by weight of the compound calculated on the total amount of the particulate carrier. 5. The method according to claim 1, wherein the amphoteric compound is a betaine. 6. The method according to claim 5, wherein the amphoteric compound is cocoamide propyl betaine. 7. The method according to claim 1, wherein the alkyl polyglycoside is a C8-C18 alkyl polyglycoside. 8. The method according to claim 1, wherein the alkyl polyglycoside is a C8-C12 alkyl polyglycoside. 9. The method according to claim 1, wherein the ethoxylated triglyceride is a C8-C20 triglyceride. 10. The method according to claim 1, wherein the ethoxylated triglyceride is a C14-C18 triglyceride. 11. The method of claim 3, wherein the air entrainment agent comprises a vinsol resin, a fatty acid salt, a rosin soap, or a sulfonated lignin salt. 12. The method of claim 1, wherein the compound is selected from the group consisting of: an amphoteric, an ester, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof. 13. The method of claim 12, wherein the compound is selected from the group consisting of: an amphoteric, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof. 14. The method of claim 1, wherein the step of dispersing separately comprises dry blending, nebulizing, spraying, or misting the compound onto the carrier. 15. A composition for improving air entrainment, comprising: a compound selected from the group consisting of: an amphoteric, an alkyl polyglycoside, an ester, an ethoxylated triglyceride, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof, wherein the compound is dispersed separately on a particulate carrier comprising limestone and added to a cementitious mixture. 16. The composition according to claim 15, incorporated into a concrete structure. 17. The method of claim 15, wherein the compound is selected from the group consisting of: an amphoteric, an ester, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof. 18. The method of claim 17, wherein the compound is selected from the group consisting of: an amphoteric, a fatty alcohol, an alkoxylated fatty alcohol, an alkoxylated polyhydric fatty alcohol, and mixtures thereof. 19. The method of claim 15, wherein the step of dispersing separately comprises dry blending, nebulizing, spraying, or misting the compound onto the carrier.
