Low-alkali and alkali-resistant cement and preparation method thereof
The invention discloses low-alkali and alkali-resistant cement and a preparation method thereof. The low-alkali cement is prepared from 700 to 800 parts of limestone, 100 to 150 parts of riverbed stripping clay, 80 to 100 parts of sandstone, 75 to 80 parts of modified phosphogypsum, 70 to 80 parts of bauxite, 60 to 70 parts of coal gangue, 50 to 70 parts of iron tailings and 30 to 40 parts of mixed hole plugging material, the mixed hole plugging material comprises 38-42% of modified plastic powder, 32-35% of gelatin powder and 25-28% of a hole plugging agent. The preparation method comprises the following steps: S1, taking limestone, riverbed stripping clay, sandstone and iron tailings, and sequentially crushing, mixing and calcining in a kiln to obtain clinker; s2, crushing modified ardealite, bauxite and coal gangue, mixing with the clinker in S1, and bagging to obtain a semi-finished product material; and S3, mixing the modified plastic powder, the gelatin powder and the hole plugging agent in the filling material, performing mixing and low-temperature crushing, performing sealed packaging, and putting the obtained product into a bagged semi-finished product material. On the premise of low alkalinity, the product not only ensures the yield and low cost of cement, but also has the effect of resisting saltpetering.
本发明公开一种低碱抗碱水泥及其制备方法，低碱水泥包括石灰石700～800份、河床剥离粘土100～150份、砂岩80～100份、改性磷石膏75～80份、铝矾土70～80份、煤矸石60～70份、尾铁矿50～70份、混合堵孔材料30～40份；混合堵孔材料包括改性塑胶粉38～42%、明胶粉32～35%、堵孔剂25～28%。S1、取：石灰石、河床剥离粘土、砂岩、尾铁矿，依次粉碎、混合和入窑煅烧，得到熟料；S2、将改性磷石膏、铝矾土、煤矸石进行粉碎后，与S1中的熟料进行混合，并装袋得到半成品料；S3、混合填充材料中的改性塑胶粉、明胶粉、堵孔剂，经混炼、低温破碎制成之后密封包装，并放置入袋装半成品料中。本产品在低碱性的前提下，既保证水泥的产量和低成本，又能起到抗泛碱的效果。
