Green and environment-friendly recycled concrete preparation method
The invention belongs to the technical field of building materials, and particularly relates to a green and environment-friendly recycled concrete preparation method. The preparation method comprises the following steps: S1, crushing and screening waste concrete to obtain prefabricated body soil particles; S2, putting the prefabricated body soil particles and waste PET plastic into a heating tank, heating the heating tank, and then separating the prefabricated body soil particles and plastic liquid through a metal filter screen to obtain concrete particles; S3, mixing the concrete particles, the plastic particles and the fine aggregate to obtain a first mixture, and mixing ordinary Portland cement, an air entraining agent, a water reducing agent and a silane coupling agent to obtain a second mixture; and S4, sequentially adding the second mixture and the first mixture into water, and fully stirring and mixing to obtain recycled concrete. The preparation method is simple, and the prepared recycled concrete is good in mechanical property, good in impermeability and not prone to cracking.
本发明属于建筑材料技术领域，具体的说是一种绿色环保型再生混凝土制备方法，包括以下步骤：S1：对废弃的混凝土进行破碎、筛选，得到预制体土粒；S2：将预制体土粒和废弃PET塑料投入到加热罐中，对加热罐进行加热，之后，将预制体土粒和塑料液使用金属滤网进行分离，得到混凝土粒；S3：将混凝土粒、塑料粒和细骨料进行混合，得到混合料一；将普通硅酸盐水泥、引气剂、减水剂和硅烷偶联剂进行混合，得到混合料二；S4：将混合料二和混合料一依次加入到水中，充分搅拌、混合，得到再生混凝土；本发明制备方法简单，制备得到的再生混凝土力学性能好、抗渗性能好，不易开裂。
