High-performance self-compacting concrete and preparation method thereof
The invention provides high-performance self-compacting concrete and a preparation method thereof.The high-performance self-compacting concrete is prepared from 250-300 parts of cement, 850-1200 parts of aggregate, 12-22 parts of polycarboxylate superplasticizer and 180-220 parts of mixing water, the aggregate is a composition of natural aggregate and recycled aggregate, and the mass ratio of coarse aggregate to fine aggregate is 1: 0.8; the recycled aggregate is prepared from waste building concrete, waste stainless steel gauze, waste rock wool boards, auxiliary materials and activating fluid, the recycled aggregate prepared through recycling of waste buildings and activating treatment is excellent and stable in performance, the water absorption rate is obviously reduced, the structure is compact and firm, natural aggregate can be partially or completely replaced, and the service life of the recycled aggregate is prolonged. The concrete processing has obvious economic benefits, the mechanical property of a concrete product is stable, the core performance competitiveness of the product is guaranteed, and the concrete processing agent is worthy of popularization and application.
本发明提出了一种高性能自密实混凝土及其制备方法，包括水泥250‑300份、骨料850‑1200份、聚羧酸高效减水剂12‑22份、拌合水180‑220份，其中，骨料为天然骨料、再生骨料的组合物，且，粗骨料和细骨料质量占比为1:0.8；再生骨料由废弃建筑混凝土、废弃不锈钢纱网、废弃岩棉板、辅料、活化液制成，本申请通过回收利用废弃建筑物，活化处理，制得的再生骨料性能优异稳定，吸水率明显降低，结构致密坚固，可部分或全部替代天然骨料，用于混凝土加工具有显著的经济效益，且混凝土产品力学性能稳定，产品核心性能竞争力有保证，值得推广应用。
