Synthesis and Properties of Polycarboxylate-Type High Range Water-Reducer

Abstract:

A series of polycarboxylate-type water-reducers (MPCs) had been developed and tested. Through molecular design, macromers of polyethylene glycol unsaturated carboxylic esters, and other derivative of unsaturated vinyl monomer containing the carboxylic groups，sulphonic groups， graft groups of alkyleneglycol was introduced as the chemical structure unit of MPCs. The copolymers MPC-2 contained long and short PEO chains and ionic groups, possessed a high dispersing and good slump retaining behavior. Therefore, MPCs can be used as high range water-reducers to prepare high-flowing concrete, high-strength high performance concrete and high-durability concrete.
