细水泥灌浆材料改性研究

Study on Changing Characteristic of Fine Cement Grout

介绍了细水泥浆液及其结石的物理力学特性（粘度、稳定性、凝结时间、抗压和抗渗强度等）的改性研究成果。通过对细水泥浆液中掺入外加剂和改变制浆工艺来改善其相关性能，以获得具有一定流动度、更高的扩散性和渗透能力的稳定性浆液，从而使细水泥灌浆材料在对微细裂隙的帷幕和固结灌浆中得到更广泛的应用。

The study results on mechanical properties of fine cement grout and its calculus, including cohesion, stability, setting time, compressive resistance and impervious strength, etc., are introduced in the paper. Through altering technics of producing fine cement paste and adding additives, a stable grout with better flowability, high diffusivity and permeability can be obtained. It can be widely used to fine fissure′s curtain and consolidation grouting.
