摘要

A new type of polycarboxylate superplasticizer with high dispersibility was synthesized by the method of free radical polymerization and the hydrothermal reaction. The synthetic process optimized the influencing factors of reaction had been discussed, including proportion of acid and ether, reaction temperature, initiator concentration, heat preservation time and additive. The dispersibility of new product was superior under the condition of low water/cement ratio, testing by gel permeation chromatography and C60 self-compacting concrete. The new product had already been used in Tianjin Goldin 117 Mega Tower project. The performance of C70 fresh mixed self-compacting concrete, which was added with new product, was very excellent in Tianjin Goldin 117 Mega Tower project, and was satisfied with the design code for high-strength self-compacting concrete in China. It is possible to realize industrial production.
