METHOD OF REDUCING STICKINESS OF CEMENTITIOUS COMPOSITIONS
The present invention provides a method and admixture composition for making hydratable cementitious compositions, ones believed to have much less stickiness in comparison to prior methods. Decreased stickiness in concrete mixes means that they are easier to pour or to cast into place, as well as easier to finish. Dispersant carboxylate polymers of the invention having this ability are characterized by possessing two different, relatively short chain lengths of polyalkyleneoxide units and low weight-average molecular weights.
