Performance of a Slow-Release Type Carboxylic Polymer and its Application

Abstract:

Article Preview

A slow-release type carboxylic polymer(SLPC) is synthesized with the monomer mixture at a certain Molecule ratio of methacrylic acid, methoxy polyethylene glycol methacrylate and polyethylene glycol di-methacrylate. Test results of the fluidity, Zeta potential and adsorption in cement paste show that the polymer SLPC has the remarkable anti-adsorbing and high fluid-retaining ability for enhancing fluidity of cement paste as time elapsed, concrete experimental results indicated that it could be used to substitute 30~50% polycarboxylic type water-reducer in the same quality for preparing high workability concrete and controlling its slump loss.
