Preparation method of phosphogypsum slag-based cement
The invention discloses a preparation method of phosphogypsum slag-based cement. The method comprises the following steps: 1, carrying out neutralization reaction treatment on phosphogypsum by using lime; step 2, drying, dehydrating and grinding the prepared phosphogypsum; and 3, uniformly mixing the prepared phosphogypsum with ultrafine blast furnace slag, a Portland cement clinker and a coagulant according to a mass ratio of (15-20%):(75-85%):(1-5%):(1-2%) to obtain the phosphogypsum slag-based cement material. Compared with the prior art, the method has the advantages of turning waste intowealth, being economical and environmentally friendly and the like, and is simple in preparation process, easy to operate and low in cost. The prepared phosphogypsum slag-based cement is high in compressive strength, short in setting time, low in cost, energy-saving and environment-friendly, and has a wide application prospect.
本发明公开了一种磷石膏矿渣基水泥的制备方法，方法步骤如下步骤一、使用石灰对磷石膏进行中和反应处理；步骤二、将制得的磷石膏干燥脱水并粉磨；步骤三、将制得的磷石膏与超细高炉矿渣、硅酸盐水泥熟料、促凝剂，按质量百分比15％—20％:75％—85％:1％—5％:1％—2％进行混合均匀，获得所述磷石膏矿渣基水泥材料。与现有技术相比，本发明具有变废为宝、经济环保等优点，且制备工艺简单、易于操作、成本低廉。制备的磷石膏矿渣基水泥的抗压强度高、凝结时间短，并且成本低、节能环保，具有广阔的应用前景。
