Abstract


A low shrinkage and viscosity-reducing type polycarboxylate superplasticizer was synthesized with maleic anhydride (MAH), diethylene glycol monobutyl ether (DGBE) and methoxypoly (ethylene glycol) methacrylate (MPEGnMA). The surface tension, early shrinkage of concrete, cement paste and application performance in concrete (slump spread, T50, V-funnel) were measured. The results show that the polycarboxylate superplasticizer we prepared has good low shrinkage and excellent viscosity-reducing capability for concrete.
