Recycled aggregate backfill concrete for deep foundation pit and preparation method of recycled aggregate backfill concrete
The invention relates to the technical field of buildings, and particularly discloses recycled aggregate backfill concrete for a deep foundation pit and a preparation method of the recycled aggregate backfill concrete. The invention relates to recycled aggregate backfill concrete for a deep foundation pit, which is characterized in that the recycled aggregate backfill concrete for the deep foundation pit is prepared from the following components in parts by mass: 180 to 210 parts of cement, 400 to 500 parts of recycled powder, 500 to 600 parts of recycled fine aggregate, 1200 to 1300 parts of recycled coarse aggregate, 5.7 to 6.3 parts of water reducing agent, 17 to 23 parts of additive and 190 to 240 parts of water, the additive is prepared from agar, isopropyl trititanate and vinyl triethoxy silane. The preparation method of the recycled aggregate backfill concrete for the deep foundation pit comprises the step of uniformly mixing all the materials to obtain the recycled aggregate backfill concrete for the deep foundation pit. The utilization rate of the waste construction waste is increased, and the workability, permeability resistance and compressive strength of the recycled aggregate backfill concrete are enhanced.
本发明涉及建筑技术领域，具体公开了一种深基坑再生骨料回填混凝土及其制备方法。一种深基坑再生骨料回填混凝土，其特征在于，以深基坑再生骨料回填混凝土的质量份数计，包括180~210份水泥、400~500份再生粉体、500~600份再生细骨料、1200~1300份再生粗骨料、5.7~6.3份减水剂、17~23份外加剂、190~240份水；外加剂包括琼脂、异丙基三钛酸酯和乙烯基三乙氧基硅烷。一种深基坑再生骨料回填混凝土的制备方法，在于将各物料混匀，得深基坑再生骨料回填混凝土。本申请既提高了废弃的建筑垃圾的利用率，又增强了再生骨料回填混凝土的工作性、抗渗透性和抗压强度。
