Phosphogypsum self-leveling mortar and preparation method thereof
The invention discloses phosphogypsum self-leveling mortar and a preparation method thereof. Raw materials for preparing the phosphogypsum self-leveling mortar comprise phosphogypsum and red mud and do not comprise cement. The preparation method comprises the following steps of: mixing the phosphogypsum with the red mud, performing calcining and ball-milling; and mixing the ball-milled phosphogypsum and red mud with aggregate, a retarder, a defoaming agent, a water-retaining agent, a water reducing agent and redispersible latex powder. According to the phosphogypsum self-leveling mortar disclosed by the invention, by adding the phosphogypsum and the red mud, zero addition of cement and the resource reutilization of the two solid wastes, namely the phosphogypsum and the red mud, are realized, and the raw material cost of the self-leveling mortar is greatly reduced.
一种磷石膏自流平砂浆及其制备方法。所述磷石膏自流平砂浆的制备原料包括磷石膏和赤泥，并且不包括水泥。所述制备方法包括：将所述磷石膏与所述赤泥混合，煅烧，球磨；以及将球磨后的磷石膏与赤泥与骨料、缓凝剂、消泡剂、保水剂、减水剂和可再分散性乳胶粉混合。本申请的磷石膏自流平砂浆通过添加磷石膏和赤泥，实现了水泥的零添加和磷石膏和赤泥这两种固体废弃物的资源再利用，而且极大地降低了自流平砂浆的原料成本。
