Steel slag blending type solid waste-based sulphoaluminate cement-based anti-static self-leveling material
The invention belongs to the field of anti-static self-leveling materials, and provides a steel slag blending type solid waste-based sulphoaluminate cement-based anti-static self-leveling material which comprises solid waste-based sulphoaluminate cement or iron aluminate cement clinker, steel slag sand and an additive, the preparation method of the solid waste-based sulphoaluminate cementing material or iron aluminate cementing material comprises the following steps: mixing dolomite tailing powder or iron tailings, steel slag powder, fly ash and desulfurized gypsum, and grinding until the particle size of a cement raw material is less than 80 microns; crushing residues obtained after pyrolysis of municipal sludge, and mixing the crushed residues with the cement raw material to obtain a mixed raw material; and homogenizing and precipitating the cement raw material or the mixed raw material, and calcining at 1230-1320 DEG C to prepare the sulphoaluminate cement or iron aluminate cement clinker. The inorganic cementing material terrace prepared by the invention has the advantages of low cost, environmental protection, static prevention, long service life and the like, and has wide market prospects and practical application significance.
本发明属于防静电自流平材料领域，提供了一种钢渣调和式固废基硫铝酸盐水泥基防静电自流平材料，包括：固废基硫铝酸盐水泥或铁铝酸盐水泥熟料、钢渣砂和外加剂；所述固废基硫铝酸盐胶凝材料或铁铝酸盐胶凝材料的制备方法包括：将白云石尾矿粉末或铁尾矿、钢渣粉、粉煤灰、脱硫石膏混合后，粉磨至水泥生料粒径在80μm以下；将市政污泥进行热解后的残渣经过破碎，与所述水泥生料混合，得到混合生料；将所述水泥生料或混合生料进行均化、沉化后在1230℃‑1320℃内进行煅烧，制备成硫铝酸盐水泥或铁铝酸盐水泥熟料。本发明制备的无机胶凝材料地坪具有低成本、环保、防静电、长寿命等优点，具有广阔的市场前景和实际应用意义。
