摘要
镁渣矿物属于介稳的高温型结构,结构中存在活性的阳离子,所以,镁渣本身具有很高的水化活性,水化后生成水化硅酸钙凝胶.镁渣作为碱胶凝材料是可行的,镁渣中的[SiO4]4-更易丢失,链断裂,形成类似于有机-无机杂化物的结构,在镁渣中掺入一定的硅酸盐水泥或磨细硅酸盐水泥熟料和磨细矿渣,以提高镁渣胶凝材料的耐久性.镁渣作为砂浆的胶结材料是非常理想的,镁渣不但可以提高砂浆的和易性,而且还可以提高砂浆的强度和耐久性.镁渣中掺入一定量的轻骨料,可制作轻质保温墙体材料或制成屋面材料.
Magnesium is a mineral residue in the high- temperature metastable structure, activity in the structure of the cation, magnesium slag itself with very high activity hydration, hydration could be the last generation calcium silicate gel. Magnesium slag as a base cementitious materials is feasible, magnesium residue [ SiO4 ]4- more loss, strand breaks, similar to the formation of organic- inorganic hybrid of structure, but the proposed incorporation in the slag in the magnesium silicate cement or cement clinker to enhance magnesium slag Cementitious Materials Durability. Magnesium as a slag cement mortar is ideal material, magnesium slag not only can improve the workability , but also can improve the strength and durability of mortar. Magnesium Slag brought a certain amount of lightweight aggregate, wall insulation can be made of light materials or manufactured roofing materials.
