Low-carbon super sulfate cement and preparation method thereof and cement mortar
The invention provides low-carbon super sulfate cement and a preparation method thereof and cement mortar. The low-carbon super sulfate cement comprises the following components in percentage by mass: 10-40% of titanium gypsum; 15%-30% of cement clinker; 20%-40% of mineral powder; 5%-10% of steel slag; 5%-10% of titanium extraction tailings; 1%-5% of vanadium slag; 2%-10% of fly ash; 0.5%-1% of an exciting agent; and 0.5%-1% of a water reducing agent. The titanium gypsum, the steel slag, the titanium extraction tailings, the vanadium slag and other industrial solid wastes are matched with the cement clinker, the mineral powder, the fly ash, the exciting agent and the water reducing agent according to a certain proportion, the use amount of the titanium gypsum is 10% or above, a large amount of the titanium gypsum and other industrial waste residues are utilized, and pollution of the industrial waste to the environment is reduced; meanwhile, the early mechanical property of the material can be improved, and the 28d chloride ion diffusion coefficient is also reduced.
本发明提供了一种低碳型超硫酸盐水泥及其制备方法，以及水泥砂浆。本发明提供的低碳型超硫酸盐水泥，包括以下质量比的组分：钛石膏10％～40％；水泥熟料15％～30％；矿粉20％～40％；钢渣5％～10％；提钛尾渣5％～10％；钒渣1％～5％；粉煤灰2％～10％；激发剂0.5％～1％；减水剂0.5％～1％。本发明采用钛石膏、钢渣、提钛尾渣及钒渣等工业固废与水泥熟料、矿粉、粉煤灰、激发剂和减水剂以一定比例搭配，其中，钛石膏的用量在10％以上，大量利用了钛石膏及其它工业废渣、降低工业废弃物对环境的污染，同时还能够提升材料的早期力学性能，且还降低了28d氯离子扩散系数。
