Coal gangue-based cementing material and preparation method thereof
The invention relates to a coal gangue-based cementing material and a preparation method, on one hand, the coal gangue-based cementing material comprises the following components in parts by weight: 1-60 parts of coal gangue, 100-150 parts of mineral powder, 5-10 parts of steel slag powder, 5-20 parts of desulfurized fly ash, 10-30 parts of quick lime, 10-15 parts of an alkali activator and 3-18 parts of an activator, the coal gangue-steel slag activated material with high active components and uniform dispersion is formed through the activating agent, the ball-milled activated steel slag powder and the coal gangue, so that a gel network framework is formed, other components are matched with the alkaline exciting agent to fill the framework, and the early strength of the gel material is improved.
本发明涉及一种煤矸石基胶凝材料及制备方法，第一方面，本申请涉及一种煤矸石基胶凝材料，包括以下按重量份数计的组分：煤矸石1‑60份、矿粉100‑150份、钢渣粉5‑10份、脱硫灰5‑20份、生石灰10‑30份、碱激发剂10‑15以及活化剂3‑18份，本发明通过活化剂和球磨活化钢渣粉和煤矸石，形成活性成分高且分散均匀的煤矸‑钢渣活化料，以便于形成凝胶网络骨架，其它组成成分配合碱性激发剂的作用将骨架进行填充，从而提高该凝胶材料的早期强度。
