CONCRETE ADMIXTURE AND PRODUCTION METHOD
A method of enhancing efficiency of a batching and/or mixing process for a concrete cementitious composition, includes adding an admixture containing dispersant molecules that bind very rapidly with cement particles and provide a dispersing effect and initial slump during the mixing process, wherein the dispersing effect diminishes rapidly. A multi-component admixture system for cementitious compositions includes: an ultrafast dispersant that binds very rapidly with cement particles, providing a dispersing effect and initial slump, wherein the dispersing effect diminishes rapidly; a general water reducing cement dispersant for providing workability; and, a latent dispersant copolymer having moieties capable of undergoing base-promoted hydrolysis to generate active cement binding sites over time, to extend slump and workability.
