Abstract
The present invention provides exemplary additive compositions and methods whereby hydratable cementitious compositions, such as concrete, can be modified using polycarboxylate type ether or ester cement dispersant polymers of a small size, in combination with at least one alkyl alkoxylate type surface active agent which typically hitherto is considered detergent-like in generating air bubbles (heads of foam) in aqueous environments. The present inventors discovered surprisingly that such agents could be used to control air content in plastic concrete mixes in combination with the polycarboxylate type ether or ester cement dispersant polymer.
