Micro-nano composite Portland cement and preparation method thereof
The invention relates to a micro-nano composite Portland cement, which is prepared from the following raw materials by weight: 30-45 parts of limestone powder; 18 to 24 parts of slag powder; 10 to 25 parts of fly ash; 2 to 15 parts of magnesium oxide; 0.5 to 5 parts of silica powder; and 15-35 parts of a concrete catalyst. The micro-nano composite Portland cement disclosed by the invention meets the requirement of low-temperature construction, has the advantages of no calcination, environmental protection, low carbon and simple and convenient processing technology, fundamentally avoids the quality problem caused by non-uniform mixing due to addition of an anti-freezing agent, is applied to high-cold and high-altitude areas, and has good cold resistance and cold resistance.
本发明涉及一种微纳米复合硅酸盐水泥，其由包括如下重量份数的原料制备而成：石灰石粉：30‑45份；矿渣粉：18‑24份；粉煤灰：10‑25份；氧化镁：2‑15份；硅微粉：0.5‑5份；混凝土催化剂：15‑35份。本发明微纳米复合硅酸盐水泥，其满足低温施工需求，具有免煅烧，环保低碳，加工工艺简便的优点，从根本上避免添加防冻剂混拌不均产生的质量问题，应用于高寒、高海拔地区，具有良好的抗寒、耐寒性。
