High-strength alkali-resistant composite brick based on waste reutilization and preparation method of high-strength alkali-resistant composite brick
The invention relates to the technical field of building materials, in particular to a high-strength alkali-resistant composite brick based on waste reutilization and a preparation method of the high-strength alkali-resistant composite brick. Electrolytic manganese residues and solid waste generated by house demolition are selected as main raw materials, and silicon-calcium resources in the electrolytic manganese residues and the solid waste are fully utilized; solid waste is subjected to grinding and grading treatment, electrolytic manganese residues are ground to expose siliceous components, then manganese residue powder and powder are used for preparing calcined aggregate, the manganese residue powder and fine particles are mixed to form a mixture, the manganese residue powder and coarse particles are ground to form mixed powder, and an additive is added as a gelatinizing agent, so that the consumption of the electrolytic manganese residues and the solid waste is increased; the silicon components in the electrolytic manganese residues interact with materials with different silicon and calcium components in the solid waste, and calcined aggregate, a mixture and a gelling agent are formed respectively. And through extrusion forming, drying maintenance and calcination maintenance, the compression resistance and breaking strength of the composite brick are improved, and the alkali corrosion resistance is enhanced.
本发明涉及建筑材料技术领域，尤其是一种基于废料再利用的高强耐碱复合砖及其制备方法，经选用电解锰渣、房屋拆除产生的固体废弃物作为主要原料，充分利用电解锰渣、固体废弃物中硅钙质资源，利用固体废弃物研磨分级处理和电解锰渣研磨裸露硅质成分，再经锰渣粉+粉料制备煅烧骨料、锰渣粉+细颗粒拌合成拌合料、锰渣粉+粗颗粒研磨成混合粉，且加入添加剂作胶凝剂，加大了电解锰渣、固体废弃物的消耗量，实现电解锰渣中硅质成分与固体废弃物中不同硅质、钙质成分存在的物料进行相互作用，分别形成煅烧骨料、拌合料、胶凝剂。再经挤压成型，干燥养护+煅烧养护，提高复合砖的抗压、抗折强度，增强抗碱侵蚀性能。
