Abstract

PC-type copolymers were synthesized using MPEG(Polyethylene glycol methyl ether methacrylate, Mn=2080) to different mole ratios of mono-carboxylic acid(AA : Acylic acid). The mole ratios of AA were 2, 3, 4. To investigate effects of PC-type co-polymers on the hydration of cement, experiments involving FT-IR, XRD, SEM have been analysed with cement paste specimens to 1, 3, 28 day. The hydration reaction rate of cement paste was slightly delayed at 1 day, due to increase in molar ratio of [AA] / [MPEG], it was recovered in the days after.
