摘　　要：碱矿渣混凝土具有高强、快硬、低热、耐久、节能等优点,但拌合物黏度大、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问题。掺加表面活性剂是解决上述问题的重要技术途径之一。通过动电电位(ζ电位)试验,系统分析了表面活性剂品种与掺量、碱激发剂品种与掺量对矿渣颗粒动电电位的影响,为研发碱矿渣混凝土专用塑化剂提供了依据。Alkali- activated slag concrete has many excellent performances, such as high strength, rapid hardening, low heat, good durability, low energy consumption and so on but has such embarrassing problems as big mixture viscosity and excessive hardened concrete shrinkage. So adding certain amount of surfactant is an important technical measure to the above problems. By ξ potential test, the paper explains about the effect of the different surfactants and activator on ξ potential. The study provides an important theoretic foundation for the development of the plasticizers of alkali -activated slag concrete.
