Production process for preparing regenerated building material from building waste
The invention relates to the technical field of building material recycling and reusing, in particular to a production process for preparing a recycled building material from building waste, which comprises the following steps: normalizing various pollution-free and water-free building waste to obtain raw materials, putting the raw materials into a jaw crusher for crushing treatment to obtain aggregate, and recycling the aggregate to obtain the recycled building material. The preparation method comprises the following steps: removing metal substances and combustible substances in an aggregate to obtain a recycled aggregate, putting the recycled aggregate into a closed container, introducing high-temperature steam for curing, adding a modifier for high-speed mixing to obtain a modified recycled aggregate, drying the modified recycled aggregate, and cooling to obtain a finished product of the recycled building material. By means of steam curing and modification, the regenerated building material has the low crushing value index, the soil strength and deformation resistance of concrete are effectively improved, meanwhile, the regenerated building material further has the good porosity, water absorption and apparent density, and the overall performance of the regenerated building material is improved to the maximum extent.
本发明涉及建筑材料回收再利用技术领域，具体是一种建筑垃圾制备再生建筑材料的生产工艺，包括如下步骤：将各种无公害、无水湿的建筑废弃物规整，得到原料，原料置入颚式破碎机中破碎处理，得到骨料，对骨料中的金属物和可燃物进行剔除，得到再生骨料，再生骨料置入密闭容器中，通入高温蒸汽进行养护，加入改性剂进行高速混合，得到改性再生骨料，将改性再生骨料干燥处理，冷却后制得成品再生建筑材料。本发明通过蒸汽养护和改性的方式，使得再生建筑材料具有较低的压碎值指标，有效的改善了混凝的土强度和抗变形能力，同时本发明再生建筑材料还具有较佳孔隙率、吸水率、表观密度，最大化的提升了再生建筑材料的整体性能。
