Controllable low-strength material prepared from steel slag desulfurization byproducts and construction waste soil and preparation method thereof
The invention belongs to the technical field of preparation of controllable low-strength materials, and discloses a controllable low-strength material prepared from steel slag desulfurization byproducts and construction waste soil and a preparation method thereof. The material is prepared from the following raw materials in parts by mass: 40-65 parts of building residue soil, 8-20 parts of a steel slag desulfurization byproduct, 1-5 parts of cement, 6-13 parts of fly ash, 5-10 parts of slag, 0.5-5 parts of an alkali activator, 0.2-2 parts of a dispersing agent and 0.05-1 part of a thickening agent. According to the controllable low-strength material, the construction waste is used for replacing part of cement to serve as a cementing material, resource utilization of the construction waste is achieved, cement resources are saved, harm of construction engineering waste to the environment is reduced, the prepared controllable low-strength material is used for backfilling soil, cyclic utilization of the construction resources is achieved, meanwhile, the problem that a large number of steel slag desulfurization byproducts are stacked to pollute the environment is solved, and good economic benefits and social values are achieved.
本发明属于可控低强度材料制备技术领域，公开了一种利用钢渣脱硫副产物及建筑渣土的可控低强度材料及其制备方法。该材料由包含以下质量份数的原料制备而成：建筑渣土40～65份，钢渣脱硫副产物8～20份，水泥1～5份，粉煤灰6～13份，矿渣5～10份，碱激发剂0.5～5份，分散剂0.2～2份，增稠剂0.05～1份。本发明以建筑渣土替代部分水泥作为胶凝材料，既实现了建筑渣土的资源化利用，又节约了水泥资源，减小了建筑工程废物对环境的危害，且制得的可控低强度材料用于回填土，实现了建筑资源的循环利用，同时解决了大量钢渣脱硫副产物堆放污染环境的问题，具有良好的经济效益和社会价值。
