Abstract A novel anti-clay type polycarboxylate superplasticizer for sulphoaluminate cement (CPC) was synthesized via free radical copolymerization using the ammonium persulfate (APS) as initiator, and acrylic acid (AA) and cinnamic acid (CINN), isoamyl alcohol polyoxyethylene ether (TPEG),2-acrylamido-2-methyl propane sulfonic acid (AMPS) as monomers. By single factor variable method, the effects of CINN dosage, initiator dosage, acid ether ratio and reaction temperature on the performance of CPC were studied. The results showed that when the initiator dosage was 0.25% of TPEG mass, n(TPEG)∶n(AA)∶n(AMPS)∶n(CINN)=1∶5∶0.3∶0.25 and the reaction temperature was 85 ℃, the performance of CPC was the best. When the dosage of bento-nite was 5% of cement mass and the dosage of CPC was 0.75%, the initial fluidity of cement paste can attain as high as 261 mm, and the fluidity of cement paste still reached 235.5 mm two hours later. Infrared detection showed there were many functional groups such as carboxyl groups, hydroxyl groups and benzene groups in CPC, which were consistent with the expected structure composition. Total organic carbon test results showed that the clay absorbed CPC less than common superplasticizer for sulphoaluminate cement. ζ-potential test analysis results showed that polycarboxylate superplasticizer dispersed cement particles mainly by steric hindrance effect.
