Steel slag-based cementing material and preparation method thereof
The invention discloses a steel slag-based cementing material and a preparation method thereof, on one hand, the steel slag-based cementing material is provided and comprises the following components in parts by weight: 30-45 parts of slag powder, 30-45 parts of steel slag powder, 20-24 parts of an exciting agent and 1-5 parts of attapulgite, and on the other hand, the invention also provides the preparation method of the steel slag-based cementing material. According to the invention, the acid-base mixed composite exciting agent is adopted, hydraulic minerals in the steel slag are hydrated to form calcium hydroxide, the alkaline exciting agent in the added composite exciting agent provides an alkaline environment beneficial to the growth of the ettringite, and the alkaline exciting agent and sodium silicate jointly promote the disintegration of the steel slag and the slag glass body structure; meanwhile, calcium hydroxide and gypsum are synergistically excited to generate a stable hydration product, namely, ettringite, so that the content of free calcium oxide is greatly reduced.
本申请公开了钢渣基胶凝材料及其制备方法，一方面提供钢渣基胶凝材料，包括以下按重量份数计的组分：矿渣粉30‑45份、钢渣粉30‑45份、激发剂20‑24份以及凹凸棒土1‑5份，另一方面还提供钢渣基胶凝材料的制备方法。本发明采用酸碱混合的复合激发剂，其中，钢渣中的水硬性矿物水化形成氢氧化钙和添加的复合激发剂中的碱性激发剂提供了有利于钙钒石生长的碱性环境，而碱性激发剂和硅酸钠共同促进钢渣与矿渣玻璃体结构的解体，同时氢氧化钙又与石膏协同激发使其产生稳定的水化产物钙钒石，大大降低了游离的氧化钙含量。
