Regenerated steel fiber concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses regenerated steel fiber concrete and a preparation method thereof. The regenerated steel fiber concrete is prepared from the following raw materials in parts by weight: 250 to 350 parts of cement, 60 to 100 parts of microbead fly ash particles, 10 to 30 parts of modified steel fiber, 4 to 12 parts of ramie fiber, 900 to 1200 parts of regenerated coarse aggregate, 600 to 1100 parts of regenerated fine aggregate, 2 to 10 parts of polycarboxylic acid water reducing agent and 150 to 220 parts of water, the preparation method comprises the following steps: uniformly mixing the recycled coarse aggregate and the recycled fine aggregate to obtain a mixture A; cement and water are evenly mixed and then added, then the microbead fly ash particles, the modified steel fibers and the ramie fibers are added and evenly mixed, finally, the polycarboxylic acid water reducing agent is added, and the regenerated steel fiber concrete is prepared. According to the regenerated steel fiber concrete disclosed by the invention, through the synergistic effect of the raw materials, the concrete has the advantage of relatively high strength.
本申请涉及混凝土的技术领域，具体公开了一种再生钢纤维混凝土及其制备方法。再生钢纤维混凝土，其包括以下重量份的原料制备而成：水泥250‑350份、微珠粉煤灰颗粒60‑100份、改性钢纤维10‑30份、苎麻纤维4‑12份、再生粗骨料900‑1200份、再生细骨料600‑1100份、聚羧酸减水剂2‑10份、水150‑220份；其制备方法为：将再生粗骨料和再生细骨料混匀，得到混合物A；将水泥和水混匀后加入，再加入微珠粉煤灰颗粒、改性钢纤维、苎麻纤维，混匀，最后加入聚羧酸减水剂，制得再生钢纤维混凝土。本申请的再生钢纤维混凝土，通过原料之间的协同作用，使混凝土具有较高强度的优点。
