Method for preparing self-leveling mortar from electrolytic manganese residues through medium-temperature calcination
The invention provides a method for preparing self-leveling mortar through medium-temperature calcination of electrolytic manganese residues, and belongs to the technical field of self-leveling mortar preparation. Comprising the following steps: preparing pyrolysis electrolytic manganese residues: drying the electrolytic manganese residues, grinding, sieving, calcining the sieved electrolytic manganese residues in a muffle furnace, heating the muffle furnace to 800 DEG C, preserving heat for 120 minutes, calcining, and cooling to room temperature along with the furnace after calcining to obtain a medium-temperature calcined product, namely the pyrolysis electrolytic manganese residues; the preparation method comprises the following steps: mixing ordinary Portland cement, aluminate cement, pyrolyzed electrolytic manganese residues and fine aggregate in proportion to obtain a powder mixture; weighing tap water, a water reducing agent and sodium borate according to the proportion, and pouring into a stirrer; and pouring the powder mixture into a stirrer at a constant speed within 30 seconds, and stirring to obtain the cement-based self-leveling mortar prepared from the pyrolysis electrolytic manganese residues and used for the ground. The solid waste is used as the raw material, so that the production cost is greatly reduced.
本发明提供了一种电解锰渣经过中温煅烧制备自流平砂浆的方法，属于自流平砂浆制备的技术领域。包括如下步骤：热解电解锰渣的制备：将电解锰渣烘干后，研磨、过筛处理，将过筛后的电解锰渣放置马弗炉中进行煅烧，马弗炉中升温至800℃，保温120mi n进行煅烧，煅烧结束后随炉冷却至室温，得到中温煅烧产物热解电解锰渣；将普通硅酸盐水泥、铝酸盐水泥、热解电解锰渣、细骨料按照比例混合，得到粉料混合物；按照比例称取自来水、减水剂和硼酸钠，倒入搅拌器中；将粉料混合物在30s内匀速倒入搅拌器中，搅拌得到热解电解锰渣制备的地面用水泥基自流平砂浆。本发明利用固体废弃物作为原料，大大降低了生产成本。
