Comprehensive utilization and preparation process of building waste materials
The invention belongs to the technical field of building waste material regeneration, and discloses comprehensive utilization of building waste materials and a preparation process of the building waste materials. Comprising 50-80 parts of building waste aggregate, 10-30 parts of building waste powder, 5-20 parts of fly ash, 1-10 parts of desulfurized gypsum, 5-10 parts of lignocellulose, 10-20 parts of cement, 3-15 parts of quick lime, 1-5 parts of a water reducing agent and 8-30 parts of water. According to the invention, the building wastes are recycled, and the crushed aggregate and powder are used for preparing the regenerated building material, so that the recycled and crushed materials of the building wastes can be completely recycled. According to the recycled material disclosed by the invention, the building waste aggregate is used as the main aggregate, so that the use amount of a cementing material can be reduced, and industrial by-products such as fly ash, desulfurized gypsum and quick lime are used at the same time, so that the preparation cost is greatly reduced, and resource utilization of industrial solid wastes is also realized.
本发明属于建筑废弃料再生技术领域，公开了建筑废弃料的综合利用及其制备工艺。包括：建筑废弃料骨料50～80份，建筑废弃料粉料10～30份，粉煤灰5～20份，脱硫石膏1～10份，木质纤维素5～10份，水泥10～20份，生石灰3～15份，减水剂1～5份，水8～30份。本发明对建筑废弃料进行回收利用，将其破碎后的骨料和粉料用于制备再生建筑材料，使建筑废弃料回收破碎后的物料可以得到全部资源化利用。本发明的再生材料以建筑废弃料骨料作为主要骨料，可以减少胶凝材料的用量，并同时使用工业副产物，如粉煤灰、脱硫石膏、生石灰等，大幅度降低了制备成本，也使工业固废得到了资源化利用。
