一、简介明矾石膨胀水泥是以硅酸盐水泥熟料为主按适当比例加入天然明矾石、石膏和粒化高炉矿渣(或粉煤灰),磨细制成的,具有膨胀性能的水硬性胶凝材料,简称AEC。其特点是具有补偿收缩,后期强度高,能显著提高混凝土的抗裂防渗性能。 I. Introduction Alunite expansive cement is based on Portland cement clinker by adding an appropriate proportion of natural alunite, gypsum and granulated blast furnace slag (or fly ash), made of fine, with expansion of hydraulic properties Cementitious materials, referred to as AEC. It is characterized by a compensatory contraction, high strength late, can significantly improve the anti-cracking concrete impermeability.
