Preparation Research of Shrinkage Reducing Polycarboxylate Superplasticizer

Lin, Yanmei / Zhang, Xiaofang / Shi, Yanna

Shrinkage reducing polycarboxylate superlasticizer was synthesized with acrylic acid, isopentenol polyoxyethylene ether (TPEG) and shrinkage-reducing monomer P. Monomer P was obtained by esterification of acrylic acid with dipropylene glycol. We studied the effects of ordinary polycarboxylate superlasticizer (Point-MS) and the synthetic shrinkage reducing polycarboxylate superlasticizer (PCE1) on the shrinkage properties of cement-based materials and concrete. The research shows that the PCE1 has excellent comprehensive properties, including good dispersing performance, strong slump retention and shrinkage reduction.
