Steel slag replacement cement and method for improving early activity of steel slag replacement cement
The invention discloses steel slag replacement cement and a method for improving early activity of the steel slag replacement cement, and relates to the technical field of cement replacement. The method comprises the following steps: grinding the steel slag to obtain the steel slag with the particle size distribution; mixing the steel slag with the particle size distribution with cement according to a first proportion to obtain a first mixture; adding alkali into the first mixture according to a second proportion to obtain a second mixture; according to the method, chemical excitation can further excite the potential gelling activity of the steel slag on the basis of mechanical excitation, and when the doping amount of NaOH is 1.0%, the doping amount of mirabilite is 3.0% and the doping amount of the steel slag is 25%, the excitation effect is optimal, and the mechanical property is optimal.
本发明公开了一种钢渣替代水泥及提高钢渣替代水泥早期活性的方法,涉及水泥替代技术领域。本发明的方法包括以下步骤:对钢渣进行粉磨,获得所述粒径分布的钢渣;将所述粒径分布的钢渣按照第一比例与水泥掺量得到第一混合物;向第一混合物中按第二比例添加碱,得到第二混合物。本发明方法发现化学激发在机械激发的基础上能够进一步激发钢渣的潜在胶凝活性,NaOH掺量为1.0%,芒硝掺量为3.0%,钢渣掺量为25%时,激发效果最佳,力学性能最优。
