Low-carbon composite cementing material based on regenerated micro powder as well as preparation method and application of low-carbon composite cementing material
The invention belongs to the technical field of building solid waste recycling, and particularly discloses a low-carbon composite cementing material based on regenerated micro powder. The low-carbon composite cementing material is prepared by compounding the regenerated micro powder, the calcined clay, the cement clinker and the gypsum, and the regenerated micro powder and the calcined clay are reasonably matched for use to replace part of the cement clinker, so that a high-added-value resource utilization mode is provided for waste concrete and waste mortar in the construction waste, and the utilization rate of the cement clinker is improved. The method provided by the invention improves the reutilization rate of the regenerated micro-powder, reduces the consumption of cement clinker, is beneficial to reducing carbon emission in the cement industry, and has a good promotion effect on protecting the ecological environment and realizing carbon neutralization in the building material industry. The invention also discloses a preparation method of the low-carbon composite cementing material, and low-carbon mortar or low-carbon concrete containing the low-carbon composite cementing material.
本发明属于建筑固废回收再利用技术领域，尤其公开了一种基于再生微粉的低碳复合胶凝材料。该低碳复合胶凝材料以再生微粉与煅烧粘土、水泥熟料、石膏复配而成，通过再生微粉和煅烧粘土合理搭配使用，替代了部分水泥熟料的使用，不仅为建筑垃圾中的废弃混凝土和废弃砂浆提供了一条高附加值的资源化利用方式，提高了再生微粉的再利用率，而且降低了水泥熟料的用量，有利于降低水泥行业的碳排放，对保护生态环境和实现建材行业碳中和具有良好的推动作用。本发明还公开了上述低碳复合胶凝材料的制备方法，以及含有上述低碳复合胶凝材料的低碳砂浆或低碳混凝土。
