Abstract

Disclosed is a method of preparing a block slow releasing concrete admixture. The block polymer is prepared by a two-step synthesis method using an unsaturated monomer, an initiator, a chain transfer agent, etc., for an aqueous solution free radical copolymerization reaction. And the preparation involves high operability, easy control of the reaction, low sensitivity to reaction conditions, suitability for industrial production, etc. The spatial configuration and stretching degree of concrete admixtures in concrete multiphase system can be regulated by introducing different types and lengths of polyether side chains into the molecules. In addition, by introducing carboxylic acid hydroxy esters and crosslinking monomers into the molecular backbone, the lubrication effect and hydrophilic state of particles in the concrete multiphase system can be improved, thereby increasing the slump retention and reducing the loss. Therefore, the concrete workability can be regulated reasonably.
