Self-compacting concrete and preparation method thereof
The invention discloses self-compacting concrete and a preparation method thereof, and relates to the technical field of building materials. The concrete is prepared from the following raw materials in parts by weight: 230-260 parts of cement, 10-20 parts of cast stone powder, 30-40 parts of silica fume, 60-80 parts of coal gangue powder, 10-20 parts of volcanic ash, 40-50 parts of blast furnace slag, 750-830 parts of sand, 950-1050 parts of a construction waste regenerated material, 8-12 parts of an additive, 180-200 parts of water, 3-5 parts of nano boron fibers, 1-3 parts of waste Kevlar fibers and 1-3 parts of pyrrolidone sulfonate agent polyphenylene sulfide. 1-2 parts of fly ash fiber and 0.5-0.8 part of soluble rosin-based polyimide. The self-compacting concrete disclosed by the invention is good in compacting effect, excellent in mechanical property, sufficient in fluidity and excellent in segregation resistance, self-filling property and volume stability.
本发明公开了一种自密实混凝土及其制备方法，涉及建筑材料技术领域，是由如下按重量份计的如下原料制成：水泥230‑260份、铸石粉10‑20份、硅灰30‑40份、煤矸石粉60‑80份、火山灰10‑20份、高炉矿渣40‑50份、砂750‑830份、建筑垃圾再生料950‑1050份、外加剂8‑12份、水180‑200份、纳米硼纤维3‑5份、废弃凯夫拉纤维1‑3份、吡咯烷酮基磺酸盐剂聚苯硫醚1‑3份、粉煤灰纤维1‑2份、可溶性松香基聚酰亚胺0.5‑0.8份。本发明公开的自密实混凝土密实效果好，机械力学性能佳，流动性足，抗离析性、自填充性和体积稳定性优异。
