Recycled aggregate lightweight concrete, preparation method and method for applying recycled aggregate lightweight concrete to non-bearing wall
The invention discloses recycled aggregate lightweight concrete and a preparation method thereof. The recycled aggregate lightweight concrete is prepared from the following raw materials in parts by weight: 30-50 parts of Portland cement, 10-30 parts of recycled fly ash, 50-100 parts of building recycled gravel, 40-65 parts of water, 0.3-0.5 part of a nano modifier, 0.1-0.2 part of a reinforcing agent, 0.1-0.2 part of a foaming agent, 0.1-0.2 part of a water reducing agent and 0.3-0.5 part of a toughening agent. The recycled aggregate lightweight concrete has the characteristics of no segregation, micro-expansion and self-leveling. According to the preparation method, a ground pump is adopted, and the recycled aggregate lightweight concrete is conveyed into a wall cavity of each floor through a pipeline for on-site pouring. The method has the advantages of short construction period, less labor, low cost, simple construction, civilized production and the like, and the poured wall body has excellent overall performances of high strength, small volume weight, heat preservation, sound insulation, heat insulation, water resistance and the like.
本申请公开了一种再生骨料轻质混凝土及其制备方法，其原料的重量组份为：硅酸盐水泥30‑50份、再生粉煤灰10‑30份、建筑再生砂石50‑100份、水40‑65份、纳米改性剂0.3‑0.5份、增强剂0.1‑0.2份、发泡剂0.1‑0.2份、减水剂0.1‑0.2份、增韧剂0.3‑0.5份。该再生骨料轻质混凝土具有不离析、微膨胀、自流平的特点。其制备方法采用地泵，通过管道将该再生骨料轻质混凝土输送到每层楼的墙体空腔内进行现场浇注。该方法具有工期短、用工少、成本低、施工简单、文明生产等优点，所浇注的墙体具有强度高、容重小、保温、隔音、隔热防水等优良的整体性能。
