Recycled aggregate concrete as well as preparation method and application thereof
The invention provides recycled aggregate concrete and a preparation method thereof, and belongs to the field of concrete. According to the invention, mixed construction waste and engineering produced soil are utilized at the same time, the mass ratio of the construction waste in the aggregate is 100%, the working performance and mechanical performance of the recycled concrete reach the performance of pure natural aggregate concrete, and by using the recycled material, not only can the consumption of natural gravel by the concrete structure be reduced, but also the cost is reduced. The dilemma of shortage of natural gravel resources at present is relieved, emission reduction of a large amount of solid waste can be achieved, a large amount of land occupied by construction waste stacking is saved, and social, economic and environment-friendly benefits are remarkable; organic-inorganic materials are hybridized to prepare the modifier, the film-forming hydrophobic characteristic of the organic materials is reserved, the pozzolanic activity of the inorganic materials is achieved, the cohesiveness of a recycled aggregate-cement mortar interface transition area is improved, and then the overall mechanical property of the recycled aggregate concrete is improved.
本发明提供了一种再生骨料混凝土及其制备方法，属于混凝土领域。本发明同时利用混合建筑垃圾和工程产出土，且建筑废弃物在骨料中的质量占比为100％，再生混凝土的工作性能和力学性能达到纯天然骨料混凝土的性能，使用再生材料不仅可以降低混凝土结构对天然砂石的消耗，缓解目前天然砂石资源短缺的困境，还可以实现大宗固体废弃物减排，节约建筑垃圾堆放所占大量土地，社会经济环保效益显著；使用有机‑无机材料进行杂化制备改性剂，既保留有机材料成膜疏水的特性，又有无机材料的火山灰活性，提高再生骨料‑水泥砂浆界面过渡区粘结性，进而提升再生骨料混凝土整体力学性能。
