Green ultrahigh-performance cement-based composite material and preparation method thereof
The invention provides a green ultra-high performance cement-based composite material and a preparation method thereof, and relates to the technical field of solid waste resource utilization. The green ultra-high performance cement-based composite material provided by the invention is prepared from the following raw materials in parts by weight: 324 to 720 parts of cement, 1 to 396 parts of calcined engineering residue soil, 100 to 260 parts of silica fume, 450 to 1350 parts of sand, 120 to 250 parts of water, 25 to 50 parts of a water reducing agent, 0 to 600 parts of stone and 0 to 300 parts of steel fiber. According to the invention, the engineering residue soil is used as the cement admixture, firstly, the cement consumption can be reduced, so that carbon emission and energy consumption are reduced, and carbon peak reaching and carbon neutralization are realized; secondly, resource utilization of the engineering residue soil can be achieved, land resources wasted due to landfill are saved, and sustainable development is achieved; and moreover, the cost of the cement-based composite material can be reduced to a certain extent, and the application range of the ultrahigh-strength cement-based composite material is expanded.
本发明提供了一种绿色超高性能水泥基复合材料及其制备方法，涉及固体废弃物资源化利用技术领域。本发明提供的绿色超高性能水泥基复合材料，按重量份数计，制备原料包括水泥324～720份，煅烧后工程渣土1～396份，硅灰100～260份，砂450～1350份，水120～250份，减水剂25～50份，石子0～600份，钢纤维0～300份。本发明将工程渣土作为水泥掺合料，首先，可以减少水泥用量，从而减少碳排放和能源消耗，实现碳达峰与碳中和；其次，可以实现工程渣土的资源化利用，节约因填埋浪费的土地资源，实现可持续发展；而且，可在一定程度降低水泥基复合材料的成本，扩大超高强水泥基复合材料的应用范围。
