Clinker-free solid waste system cement and manufacturing method thereof
The invention provides clinker-free solid waste system cement and a preparation method thereof, and the clinker-free solid waste system cement is prepared from the following raw materials by mass: 10-20% of gypsum, 10-20% of steel slag, 60-75% of slag, and 0.1-0.5% of a steel slag-slag early activity strength activator. The problems that the cement is low in early strength, easy to carbonize, poor in weathering resistance and the like can be solved by adding the steel slag-mineral slag early activity strength activator, and in addition, the clinker-free solid waste system cement has good grain composition and lower water demand; and the mortar and the concrete can be ensured to have strength and durability meeting engineering requirements by adopting a relatively low water-binder ratio and water consumption. And the cement does not use clinker but uses solid waste, so that the environment can be protected, and the production cost can be saved.
本发明提供一种无熟料固废体系水泥及其制备方法，该熟料固废体系水泥由以下原料制备而得：石膏10～20％，钢渣10～20％，矿渣60～75％，钢渣‑矿渣早期活性强度激发剂0.1～0.5％，所述百分比均为质量百分比。添加了钢渣‑矿渣早期活性强度激发剂可以解决该水泥早期强度低，易碳化，抗风化能力差等问题，另外，无熟料固废体系水泥具有良好的颗粒级配和较低的需水量，采用较低水胶比和用水量能够保证砂浆和混凝土具有满足工程要求的强度和耐久性。而且该水泥不用熟料而用固废，既可以保护环境又可以节约生产成本。
