Preparation method of recycled aggregate pervious concrete
The invention discloses a preparation method of recycled aggregate pervious concrete, which comprises the following steps: S1, mechanical crushing: carrying out mechanical crushing on waste concrete blocks by using a crusher; s2, aggregate screening: screening the crushed concrete blocks by using a vibrating screen to obtain recycled aggregate; s3, waste removal: separating light waste in the recycled aggregate by using a flotation machine, and then drying to obtain the recycled aggregate for later use; s4, quantitative weighing: weighing the dried to-be-used recycled aggregate, stones, medium sand, cement, mixing water and a water reducing agent; s5, mixing and stirring: putting the to-be-used recycled aggregate, pebbles, medium sand, cement, mixing water and a water reducing agent into a stirrer, mixing and stirring to obtain the recycled aggregate pervious concrete, crushing the aggregate, and then screening and removing light impurities such as wood and wood dust possibly adhered to the aggregate by virtue of a flotation machine to obtain the recycled aggregate pervious concrete. And the quality of subsequently prepared concrete is effectively improved.
本发明公开了一种再生骨料透水混凝土的制备方法，包括以下步骤：S1，机械破碎，将废弃的混凝土块利用破碎机进行机械破碎；S2，骨料筛分，利用振动筛对破碎后的混凝土块进行筛分，得到再生骨料；S3，废料去除，利用浮选机对再生骨料中的轻质废料进行分离，然后干燥后得到待用再生骨料；S4，定量称重，称取干燥后的待用再生骨料、石子、中砂、水泥、拌合水和减水剂；S5，混料搅拌，将待用再生骨料、石子、中砂、水泥、拌合水和减水剂放入搅拌机进行混合并搅拌，得到再生骨料透水混凝土，骨料经过破碎后再借助浮选机对骨料上可能粘附的木头、木屑等轻质杂质进行筛选去除，有效提高后续制备出来混凝土的质量。
