碱矿渣水泥及混凝土化学外加剂的研究进展

碱矿渣混凝土具有高强、快硬、低热、耐久、节能等优点,但是凝结时间短、拌合物粘度大、硬化体收缩大是制约碱矿渣水泥及混凝土应用发展的关键技术.掺化学外加剂是解决上述问题的重要技术途径,也是国内外研究者一直关注的课题.本文介绍了碱矿渣混凝土化学外加剂的研究现状,并分析了碱矿渣混凝土化学外加剂今后的研究方向.

The research progress of chemical admixture for alkali-activated slag cement and concrete

Alkali-activated slag concrete has many excellent performance, such as high strength, rapid hardening, low heat, good durability, saving energy sources and so on; But it is a mostly problem to embarrass application of alkali-activated slag cement and concrete that is short setting time, big mixture viscosity and big harden concrete shrinkage. It is an important techno-means and paid attention by domestic and overseas researchers adulterating alkali-activated slag cement and concrete with chemical admixture. The paper introduces the research progress of chemical admixture for alkali-activated slag concrete, and construes the approach of researching chemical admixture for alkali-activated slag concrete hereafter.
