Method for preparing pozzolanic admixture through manganese slag modification
The invention relates to the technical field of materials, in particular to a method for preparing a pozzolanic admixture through manganese slag modification, which comprises the following steps: homogenizing manganese slag, lithium slag, shale or clay and carbon powder in a brick and tile kiln through mechanical mixing equipment, feeding the mixture into a crusher for crushing, preparing a green brick by using forming equipment, and then feeding into a drying kiln for drying, thereby obtaining the pozzolanic admixture. And transferring into a high-temperature kiln for calcining, taking out the bricks from the kiln, cooling, and crushing to obtain the volcanic ash mixed material. Manganese slag, lithium slag and shale or clay are combined, carbon powder is introduced to serve as internal fuel, the manganese slag is subjected to high-temperature calcination modification through an existing brick and tile kiln after homogenization, crushing, green brick preparation and drying, a new production line is not needed, cost is reduced, the pozzolanic mixed material is obtained, and the physical and chemical properties of the pozzolanic mixed material are remarkably improved; the performance of the modified manganese slag meets the new standard requirement, the carbon powder plays a role of internal fuel, the calcined material is good in activity and high in silicon and aluminum content, and the performance of the calcined manganese slag is further improved.
本发明涉及材料技术领域，具体涉及一种锰渣改性制备火山灰质混合材的方法，包括以下步骤：在砖瓦窑将锰渣、锂渣、页岩或粘土、碳粉通过机械混合设备均化处理，混合物送入破碎机中破碎，再使用成型设备制得砖坯，随后送入干燥窑中烘干，转入高温窑中煅烧，砖块出窑后冷却、破碎，制得火山灰质混合材。通过将锰渣、锂渣与页岩或粘土结合，并引入碳粉作为内燃料，通过均化、破碎、制成砖坯、烘干后，利用现有的砖瓦窑对锰渣高温煅烧改性，无需新建生产线，降低成本，得到火山灰质混合材，其物理和化学性能得到显著提升，使得锰渣改性后性能达到新标准要求，碳粉起内燃料的作用，且煅烧后材料的活性好、硅和铝较高，进一步提高煅烧锰渣性能。
