Cementing material containing clay mineral
The invention discloses a cementitious material containing clay minerals. The cementitious material comprises the following components in parts by weight: 55-60 parts of clay minerals; 10-20 parts of a flue gas desulfurization byproduct; 10-20 parts of converter steel slag; 5-10 parts of a modifier; the modifier is prepared from the following components in parts by weight: 20 to 25 parts of calcium silicate, 10 to 25 parts of tricalcium aluminate, 1 to 5 parts of nano aluminum oxide, 10 to 15 parts of tricalcium silicate, 5 to 15 parts of tetra calcium aluminoferrite, 2 to 6 parts of methyl polycarboxylic acid and 1 to 5 parts of vinyl acetate. Compared with the existing cement clinker or solid waste-based cementing material, the cementing material containing the clay mineral provided by the invention is prepared from the clay mineral, the desulfurization by-product, the steel slag, the modifier and the like as raw materials, and the cement clinker and slag are not added, so that the cost of the raw materials is greatly reduced, and the cementing material containing the clay mineral has good compressive strength.
本发明公开了一种含粘土矿物的胶凝材料，包括如下重量份的组分：粘土矿物55‑60份；烟气脱硫副产物10‑20份；转炉钢渣10‑20份；改良剂5‑10份；所述改良剂包括如下重量份的组分：硅酸钙20‑25份，铝酸三钙10‑25份，纳米三氧化二铝1‑5份，硅酸三钙10‑15份，铁铝酸四钙5‑15份，甲基聚羧酸2‑6份，乙酸乙烯酯1‑5份。本发明提供的含粘土矿物的胶凝材料与现有的水泥熟料或者含固废基胶凝材料相比，本发明的胶凝材料的原料采用粘土矿物、脱硫副产物、钢渣和改良剂等成分组成，不添加水泥熟料和矿渣，极大的降低了原料成本，且具有良好的抗压强度。
