Recycling method of concrete waste material and recycled concrete
The invention discloses a recycling method of a concrete waste material and recycled concrete, and belongs to the technical field of concrete preparation. According to the technical key points, the recycling method of the concrete waste material comprises the following steps: S1, humidifying and freezing; S2, pre-crushing; respectively crushing the frozen waste concrete material and the frozen waste ceramic material; S3, grinding and drying; S4, screening and mixing; respectively screening the dried waste concrete material and waste ceramic material, mixing the waste concrete material with theparticle size of more than 4mm with the waste ceramic material to serve as recycled coarse aggregate, and mixing the waste concrete material with the particle size of less than 4mm with the waste ceramic material to serve as recycled fine aggregate; and S5, preparing concrete. According to the scheme, the waste concrete material and the waste ceramic material are used for preparing the concrete so that the waste gas concrete material and the waste ceramic material are recycled, the environmental problem is effectively solved, and natural resources are prevented from being wasted.
本申请公开了一种混凝土废弃料的再生利用方法及再生混凝土，属于混凝土制备的技术领域，其技术要点是：一种混凝土废弃料的再生利用方法，包括以下步骤：S1：调湿冷冻；S2：预破碎；将冷冻后的废弃混凝土料以及废弃陶瓷料分别进行破碎；S3：研磨烘干；S4：筛分混料；对烘干后的废弃混凝土料与废弃陶瓷料分别进行筛分，将粒径大于4mm的废弃混凝土料与废弃陶瓷料混合作为再生粗骨料，粒径小于4mm的废弃混凝土料与废弃陶瓷料混合作为再生细骨料；S5：混凝土制备。通过上述方案，将废弃混凝土料与废弃陶瓷料进行混凝土的制备，实现废气混凝土料与废弃陶瓷料的再利用，有效解决环境问题的同时避免了浪费天然资源。
