Ready-mixed mortar using recycled aggregate and preparation method of wet-mixed mortar
The invention discloses ready-mixed mortar using recycled aggregate. The ready-mixed mortar comprises the following raw material components: 15-23% of cement, 8-10% of fly ash, 33-47% of recycled aggregate, 16-20% of river sand and 1.5-4.6% of an additive. The cement, the fly ash, the recycled aggregate, the river sand and the additive are uniformly mixed with water according to a scientific and reasonable ratio to obtain the ready-mixed mortar; the preparation process is simple, and the prepared ready-mixed mortar meets various performance indexes of premixed masonry, plastering and ground mortar in the latest 'Ready-Mixed Mortar' GB/T25181-2019 standard; The ready-mixed mortar is light in weight, high in early strength and good in workability, the water-retaining property is greatly improved, the construction time is prolonged, and the binding power of hardened mortar and a matrix is improved; the construction efficiency is high, and the integrality is good; and meanwhile, two industrial solid wastes, namely the construction waste and the nickel slag, are used as raw materials, so that the cost is saved, and the environment is protected favourably.
本发明公开了一种使用再生骨料的湿拌砂浆，包括以下原料组份：水泥15‑23％，粉煤灰8‑10％，再生骨料33‑47％，江砂16‑20％，外加剂1.5‑4.6％；本发明通过科学合理的配比，将水泥、粉煤灰、再生骨料、江砂和外加剂均匀与水混合，得到该湿拌砂浆，制备工艺简单，制得的该湿拌砂浆满足最新《预拌砂浆》GB/T25181‑2019标准预拌砌筑、抹灰、地面砂浆的各项性能指标；并且该湿拌砂浆重量轻、早期强度高、和易性好，保水性大大提高，可施工时间延长，提高硬化砂浆与基体的粘结力；还具有施工效率高，整体性好的优点；同时使用建筑垃圾和镍渣两种工业固体废弃物为原料，节省成本，且有利于保护环境。
