Abstract
Additives for cementitious compositions are stabilized against particle agglomeration. The additive may be provided in an aqueous liquid admixture composition for cementitious compositions that includes the additive, a polymer thickener, and water, where the particles are stabilized against agglomeration and the admixture is stabilized against physical separation. The method for stabilizing the additive against particle agglomeration utilizes a pH sensitive thickener that may be activated through neutralization of acid groups on the polymer thickener. Methods of making cementitious compositions and hardened cementitious structures using the stabilized additive and admixture are also disclosed.
