Portland cement and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to Portland cement and a preparation method thereof. The building material is prepared from the following raw materials in parts by weight: 65-75 parts of limestone, 1-2 parts of metakaolin, 1.5-2 parts of fly ash, 2.5-3 parts of silica fume, 13-17 parts of clay, 6-7 parts of bentonite, 8-15 parts of red mud, 14-15 parts of gypsum, 0.75-1.5 parts of beta-naphthalene sulfonic acid formaldehyde high concentrate, 1-1.5 parts of borax, 4-5 parts of basalt fiber, 1-2 parts of glycerol, 0.5-1 part of citric acid, 3-4 parts of polyvinyl alcohol fiber and 8-9 parts of white carbon black. According to the Portland cement, the metakaolin and the beta-naphthalene sulfonic acid formaldehyde high concentrate are added, the initial setting time and the final setting time of the cement are greatly shortened, the basalt fibers, the polyvinyl alcohol fibers and the glycerol are added, the strength of the cement is improved, meanwhile, the toughness of the cement is improved, and the cracking phenomenon in the using process is avoided.
本发明属于建筑材料技术领域，具体的涉及一种硅酸盐水泥及其制备方法。由以下重量份数的原料组成：石灰石65‑75份、偏高岭土1‑2份、粉煤灰1.5‑2份、硅灰2.5‑3份、粘土13‑17份、膨润土6‑7份、赤泥8‑15份、石膏14‑15份、β‑萘磺酸甲醛高浓缩物0.75‑1.5份、硼砂1‑1.5份、玄武岩纤维4‑5份、丙三醇1‑2份、柠檬酸0.5‑1份、聚乙烯醇纤维3‑4份以及白炭黑8‑9份。本发明所述的硅酸盐水泥，加入偏高岭土以及β‑萘磺酸甲醛高浓缩物，大大缩短了水泥的初凝及终凝时间，加入玄武岩纤维、聚乙烯醇纤维及丙三醇，在提高水泥的强度的同时，提高水泥的韧性，避免使用过程中出现开裂现象。
