Preparation method of recycled concrete and recycled concrete
The invention discloses a preparation method of recycled concrete and the recycled concrete, belongs to the technical field of concrete preparation, solves the problems of waste of concrete waste, influence on the environment and the like to a certain extent, and has the technical key points that the preparation method of the recycled concrete is characterized by comprising the following steps: S1, humidifying and freezing: adding water into the waste concrete blocks for humidifying, and placing the waste concrete blocks in a refrigeration house for freezing refrigeration, S2, mechanical crushing: mechanically crushing the frozen waste concrete blocks by using a crushing device, S3, acidification treatment: putting the crushed waste concrete material into an acid solution for reaction activation, S4, drying and grinding: cleaning and drying the acidified waste concrete material, grinding the dried waste concrete material, and performing air draft dust removal during grinding, S5, screening and mixing, and S6, concrete preparation. According to the scheme, the waste concrete material is effectively processed into the recycled aggregate, and the recycled concrete is further prepared.
本申请公开了一种再生混凝土的制备方法及再生混凝土，属于混凝土制备的技术领域，实现在一定程度上解决了混凝土废料浪费、影响环境等问题，其技术要点是：一种再生混凝土的制备方法，其特征在于，包括以下步骤：S1、调湿冷冻；将废弃混凝土块加水调湿并放置与冷库中进行冰冻制冷；S2、机械破碎；将冷冻后的废弃混凝土块利用破碎装置进行机械破碎；S3、酸化处理；将破碎后的废弃混凝土料放置入酸液中进行反应活化；S4、烘干研磨；对酸化处理后的废弃混凝土料进行清洗并烘干，烘干后对其进行研磨，并在研磨时进行抽风除尘；S5、筛分混料；S6、混凝土制备。通过上述方案，实现了有效加工废弃混凝土料为再生骨料，并进一步制成再生混凝土。
