Preparation process of manganese slag and red mud baking-free brick
The invention discloses a preparation process of a manganese slag and red mud baking-free brick. Manganese slag, red mud, water and 85% phosphoric acid are used as raw materials. The method comprisesthe following steps: mechanically crushing manganese slag and red mud through crushing and sieving, mixing the obtained powder according to a certain mass ratio, adding water, stirring to form slurry,adding a phosphoric acid solution, carrying out a phosphoric acid mixing and stirring reaction, carrying out compression molding in a brick making machine, molding a brick blank, and carrying out pressure maintaining, heat preserving and maintenance to obtain the finished baking-free brick. The preparation process is a recycling scheme for cooperatively treating manganese slag and red mud. The preparation process is simple, calcination is not needed, energy conservation and environmental protection are achieved, and the prepared manganese slag and red mud baking-free brick is high in compressive strength, low in cost and capable of being widely applied to building filling building blocks.
本发明公开了一种锰渣赤泥免烧砖的制备工艺，以锰渣、赤泥、水和85％磷酸为原料，先通过粉碎过筛将锰渣赤泥机械破碎后筛分，得到的粉末按照一定质量配比进行配料混合后，加水搅拌形成浆料，再加入磷酸溶液进行磷酸混合搅拌反应完成后，置于制砖机模压成型，砖坯成型后进行保压保温养护后得到成品免烧砖。本发明是一种协同处理锰渣和赤泥的资源化利用方案，该方案制备工艺简单、无需煅烧、节能环保，所制备的锰渣赤泥免烧砖抗压强度高，成本低廉，可广泛用于建筑填充砌块。
