Low-cost high-performance fully-recycled aggregate mortar and preparation method thereof
The invention discloses low-cost high-performance fully-recycled aggregate mortar and a preparation method thereof. The fully-recycled aggregate mortar is prepared from the following raw materials: cement, recycled brick fine aggregate, recycled concrete fine aggregate, waste rubber particles and water. The percentage contents of the cement, the recycled brick fine aggregate, the recycled concrete fine aggregate and the waste rubber particles in the total solid mass are: cement 16%-25%, recycled brick fine aggregate 14%-17%, recycled concrete fine aggregate 57%-65%, waste rubber particles 1%-3%. The water accounts for 60%-130% of the amount of the cement. The used fine aggregate is obtained by crushing and screening waste bricks, waste concrete and waste rubber, the technical performance of the recycled mortar is improved by utilizing the characteristics of the aggregate, the problems of poor flowability, poor durability and the like of the traditional recycled mortar are solved, efficient resource utilization of solid wastes is realized, and the environmental and economic benefits are remarkable.
本发明公开了一种低成本高性能全再生骨料砂浆及其制备方法。全再生骨料砂浆原料包括水泥、再生砖细骨料、再生混凝土细骨料、废弃橡胶颗粒和水，其中，水泥、再生砖细骨料、再生混凝土细骨料和废弃橡胶颗粒四者所占固体总质量的百分比含量为：水泥16％‑25％、再生砖细骨料14％‑17％、再生混凝土细骨料57％‑65％、废弃橡胶颗粒1％‑3％；其中，水占水泥用量的比重为60％‑130％。本发明使用的细骨料由废弃砖、废弃混凝土和废弃橡胶经破碎、筛分而得，利用骨料自身特性对再生砂浆技术性能进行改良，解决了传统再生砂浆流动性差、耐久性差等问题，实现固体废弃物的高效资源化利用，环境和经济效益显著。
