摘要
矿渣微粉具有一定的水化活性,掺入水泥浆体后能够明显提高水泥抗化学侵蚀性能,抗干缩,抗碳化,抗冻性等耐久性能,提高幅度基本可以达到10%左右;利用SEM,TG-DTA,XRD,压汞孔分析等方法对水泥水化物进行分析,结果表明:矿渣微粉能够吸收水泥水化产物Ca(OH)2生成C-S-H凝胶,导致降低孔径,优化孔结构,从而提高水泥石的密实度,从而改善水泥的各项性能。
Experiment of cement with ground slag shows that ground slag can improve the properties of ce-ment such as coefficient of resistance to chemical corrosion, dry shrinkage, and carbonation coef-ficient, freezing and thawing resistance by 10%. The microstructure-analysis by using SEM, TG- DTA, XRD and MIP shows that the ground slag can absorb the productions of hydrating cement: Ca(OH)2, and C-S-H gel is formed, which can refine the distribution of pore structure and increase the density of cement-stone, therefore improving the durability.
