New Type

The ethyl glycol vinyl ether polyoxyethylene ether (EPEG) is a new type of macromonomer to synthesize polycarboxylate superplasticizer (PCE), which has higher reactivity due to the unsaturated double bond and easily to polymerization. The EPEG slump retaining typed PCE can be synthesized by free radical polymerization though EPEG, acrylic acid and hydroxyethyl acrylate (HEA). The HEA had the greatest influence on slump retaining performance. High polymerization conversion rate of EPEG typed PCE was beneficial to improve the concrete performance.
