Low-clinker cement as well as preparation method and application thereof
The invention provides low-clinker cement as well as a preparation method and application thereof. The low-clinker cement comprises the following raw materials in parts by mass: 75-85 parts of blast furnace slag, 10-20 parts of gypsum, 1-10 parts of red mud and 2-5 parts of cement clinker, wherein the sum of the contents of oxides of calcium, silicon and aluminum in the blast furnace slag is greater than 80 wt%, the content of calcium carbonate in the blast furnace slag is less than or equal to 10 wt%, and the specific surface area is greater than or equal to 350 m<2>/kg. The high-activity blast furnace slag is used as a main component of the cement, the gypsum, the red mud and a small amount of the cement clinker are doped, and the alkali activity of the red mud and the blast furnace slagis fully utilized; through reasonable proportioning of several ash components, the low-clinker cement with high mechanical properties is generated through reaction under the synergistic effect of allthe components, and the use amount of the cement clinker is reduced.
本发明提供一种低熟料水泥及其制备方法和应用，所述低熟料水泥包括如下质量份的原料：高炉矿渣75～85份、石膏10～20份、赤泥1～10份、水泥熟料2～5份，所述高炉矿渣中钙、硅和铝的氧化物之和大于80wt％，所述高炉矿渣中碳酸钙的含量≤10wt％，比表面积≥350m2/kg。本发明以高活性的高炉矿渣作为水泥的主要成分，掺入石膏、赤泥和少量的水泥熟料，充分利用赤泥与高炉矿渣的碱活性，通过几种灰体组分的合理配比，在各组分协同作用下反应生成具有较高力学性能的低熟料水泥，降低水泥熟料用量。
