3D printing concrete prepared from recycled aggregate and preparation method of 3D printing concrete
The invention relates to the field of recycled concrete, and particularly discloses 3D printing concrete prepared from recycled aggregate and a preparation method of the 3D printing concrete. The 3D printing concrete prepared from the recycled aggregate is prepared from 110-140 parts of cement, 70-90 parts of gravel, 150-170 parts of the recycled aggregate, 1-1.5 parts of a water reducing agent, 0.5-1 part of an accelerator, 10-15 parts of an admixture, and 70-80 parts of water, wherein 5-20% by weight of the admixture is coated with a temperature sensitive film. According to the 3D printing concrete prepared from the recycled aggregate and the preparation method thereof, the 3D printing concrete has the advantages of relatively low hydration heat temperature and high concrete strength; and in addition, the preparation method disclosed by the invention has the advantage of reducing the unsmooth possibility of the concrete in the 3D printing process.
本申请涉及再生混凝土的领域，具体公开了一种利用再生骨料制备的3D打印混凝土及其制备方法，一种利用再生骨料制备的3D打印混凝土及其制备方法包括水泥110‑140份、砂石70‑90份、再生骨料150‑170份、减水剂1‑1.5份、速凝剂0.5‑1份、掺合料10‑15，其中重量为5%‑20%的掺合料使用温度敏感膜包覆、水70‑80份。本申请的一种利用再生骨料制备的3D打印混凝土及其制备方法，其具有水化热温度较低、混凝土强度高的优点；另外，本申请的制备方法具有降低混凝土在3D打印的过程中不流畅可能性的优点。
