high-performance comb-like pce superplasticizer and their interactions with cement particles

Abstract the effect of different macromolecules on witheirious functionality and top particles interactions with cement particles was investigated. the aa-co-apeg (n=20) comb-like copolymers were synthesized via free radical polymerization. the molecular structures of the copolymers were also characterized by ftir and tga methods. the mechanism of adsorption of sodium lignosulfonate(ls-na) and comb-like copolymer and their effects on the cement slurry was also studied. the spread values of the cement paste increased with the pce superplasticizer.
