Solid waste heat-conducting self-leveling mortar as well as preparation method and application thereof
The invention discloses solid waste heat-conducting self-leveling mortar as well as a preparation method and application thereof. Raw materials for preparing the solid waste heat-conducting self-leveling mortar comprise phosphogypsum and steel slag and do not comprise cement. The preparation method comprises the following steps of: mixing the phosphogypsum with the steel slag, performing calciningand ball-milling; and mixing the ball-milled phosphogypsum and steel slag with aggregate, a retarder, a defoaming agent, a water-retaining agent, a water reducing agent, redispersible latex powder and an optional heat-conducting material. The self-leveling mortar provided by the invention has good strength, fluidity and thermal conductivity, can be used for gap filling and upper-layer covering offloor heating pipelines, greatly saves the raw material cost of a floor heating system, and realizes resource reutilization of two solid wastes, i.e., the phosphogypsum and steel slag.
一种固废导热自流平砂浆及其制备方法和应用。所述固废导热自流平砂浆的制备原料包括磷石膏和钢渣，并且不包括水泥。所述制备方法包括：将所述磷石膏与所述钢渣混合，煅烧，球磨；以及将球磨后的磷石膏与钢渣与骨料、缓凝剂、消泡剂、保水剂、减水剂、可再分散性乳胶粉和任选地导热材料混合。本申请的自流平砂浆具有良好的强度、流动性及导热性，能够用于地暖管道间隙填充及上层覆面，而且极大地节省了地暖系统的原料成本，实现了磷石膏和钢渣这两种固体废弃物的资源再利用。
