Construction waste regenerated brick and preparation method thereof
The invention relates to the technical field of regenerated bricks, and discloses a construction waste regenerated brick which comprises the following raw materials in parts by weight: 30-45 parts of cement, 65-80 parts of fine aggregate, 55-70 parts of recycled brick coarse aggregate, 1-5 parts of polypropylene fibers, 10-20 parts of kaolin, 30-50 parts of fly ash, 1-5 parts of a water reducing agent, 1-5 parts of an early strength agent, 1-5 parts of an anti-freezing agent and 15-25 parts of water. The invention further relates to a preparation method of the construction waste regenerated brick, which comprises the steps of 1) preparing cement, fine aggregate, regenerated brick coarse aggregate, polypropylene fibers, kaolin, fly ash, a water reducing agent, an early strength agent, an anti-freezing agent and water, pre-wetting a barrel of a stirrer, then putting the regenerated brick coarse aggregate, the cement and the fine aggregate into the stirrer, pre-stirring for 2-3 minutes, uniformly stirring to obtain a mixture for later use, uniformly dispersing the polypropylene fibers into the obtained mixture, and carrying out dry mixing for 1-2 minutes to obtain mixed powder. According to the construction waste regenerated brick and the preparation method thereof, the purpose of higher strength is achieved.
本发明涉及再生砖技术领域，且公开了一种建筑垃圾再生砖，包括以下重量份数配比的原料：水泥30‑45份、细骨料65‑80份、再生砖粗骨料55‑70份、聚丙烯纤维1‑5份、高岭土10‑20份、粉煤灰30‑50份、减水剂1‑5份、早强剂1‑5份、防冻剂1‑5份和水15‑25份；一种建筑垃圾再生砖的制备方法，包括以下步骤：1)准备水泥、细骨料、再生砖粗骨料、聚丙烯纤维、高岭土、粉煤灰、减水剂、早强剂、防冻剂和水，预先润湿搅拌机筒体，然后将再生砖粗骨料、水泥及细骨料投入搅拌机中，预搅拌2～3min，拌合均匀得混合物，接着将聚丙烯纤维均匀分散入得到的混合物中，干拌1min～2min得混合粉。该建筑垃圾再生砖及其制备方法，实现了强度更高的目的。
