Environment-friendly recycled micro-powder aggregate and application thereof in concrete
The invention provides an environment-friendly recycled micro-powder aggregate and application thereof in concrete, the recycled micro-powder aggregate is of a layered structure coated in sequence, and comprises a plurality of alternately coated base material layers, repair layers and an outermost activation layer from inside to outside; wherein the mass fraction of the base material layer is 70-85 wt%, the mass fraction of the repair layer is 10-25 wt%, the mass fraction of the activation layer is 2-5 wt%, the regenerated micro-powder aggregate is used for replacing natural aggregate in concrete, and the replacement amount can reach 70-85%; the waste building materials are reasonably utilized, structure transformation and optimization activation are conducted in a targeted mode, and the prepared recycled micro-powder aggregate is compact in structure, stable in performance, excellent in mechanical parameter, low in water absorption rate, small in porosity, economical and efficient when used as concrete recycled aggregate, high in cost performance and worthy of application and popularization.
本发明提出了一种环境友好型再生微粉骨料及其在混凝土中的应用，再生微粉骨料为依次包覆的层状结构，由内至外包括多个交替包覆的基料层、修复层，以及最外层的活化层；其中，基料层质量分数占比为70‑85wt%，修复层质量分数占比为10‑25wt%，活化层质量分数占比为2‑5wt%，该再生微粉骨料在混凝土中用于天然骨料替代，替代量可达70‑85%；本申请合理利用废弃建筑物料，针对性进行结构改造和优化活化，制得再生微粉骨料结构密实，性能稳定，具有优异的力学参数，吸水率低，孔隙率小，作混凝土再生骨料应用经济高效，性价比高，值得推广应用。
