And Performance

Propylmethyl cellulose monoester of maleic acid (MAPMC) was synthesized with Propylmethyl cellulose and Maleic anhydride. A modified polyether-type superplastizer (PES) was prepared from ally polyoxyethylenether, Maleic anhydride, acrylic acid and MAPMC through a free radical polymerization. MAPMC and PES were recorded by FTIR. The fluidity of cement paste were investigated, the hydration process of cement for PES were characterized via Hydration Heat Tester. The results indicate that PES superplastizers can improve the fluidity of mortars and more capable of preventing slump loss, the hydroxy group of PES has no negative impact on cement hydration .
