Activating agent for low-carbon cement as well as preparation method and application of activating agent
The invention relates to the technical field of low-carbon cement, and particularly discloses an activating agent for low-carbon cement as well as a preparation method and application of the activating agent. The low-carbon activating agent for the cement comprises the following components in parts by weight: 5-8 parts of orthogonal sodium silicate; 4-5 parts of sodium bicarbonate; 1.5 to 2 parts of an additive; the preparation method comprises the following steps: uniformly mixing all the components to obtain the low-carbon cement activator. The application of the low-carbon cement activator comprises the following steps: uniformly mixing the low-carbon cement activator and low-carbon cement clinker according to a weight ratio of 1: (100-105), and grinding to obtain a low-carbon cement product. The activator for the low-carbon cement can improve the pozzolanic activity of iron tailings in the grinding, hydration and condensation processes of the cement and improve the yield of hydraulic products, so that the compressive strength of the finally obtained low-carbon cement product is not lower than 53.8 MPa and the breaking strength is not lower than 7.6 MPa under 28-day maintenance.
本申请涉及低碳水泥的技术领域，具体公开了一种低碳型水泥用活化剂及其制备方法和应用。一种低碳型水泥用活化剂包括以下重量份的组分：正交硅酸钠5‑8份；碳酸氢钠4‑5份；外加剂1.5‑2份；其制备方法为：将全部组分混合均匀后得到低碳型水泥用活化剂；其应用为：将低碳型水泥活化剂与低碳型水泥熟料按照1:（100‑105）的重量比混合均匀后进行粉磨，得到低碳型水泥产品。本申请的低碳型水泥用活化剂能够在水泥的粉磨、水化、凝结过程中提升铁尾矿的火山灰活性，提升水硬性产物的产量，使最终得到的低碳型水泥产品在28d养护下的抗压强度不低于53.8MPa，抗折强度不低于7.6MPa。
