Iron tailing sand recycled concrete under synergistic effect of nano metakaolin and preparation method of iron tailing sand recycled concrete
The invention discloses iron tailing sand recycled concrete under the synergistic effect of nano metakaolin and a preparation method of the iron tailing sand recycled concrete. The nano recycled concrete is prepared from the following raw material components in parts by weight: 402 to 447 parts of cement, 0 to 45 parts of nano metakaolin, 320 to 645 parts of natural fine aggregate, 0 to 323 parts of iron tailing sand, 549 parts of natural coarse aggregate, 549 parts of recycled coarse aggregate and 190 to 220 parts of water. The utilization rate of the iron tailing sand and the recycled coarse aggregate is increased, the mechanical property of the recycled concrete is improved, the recycled concrete has a more compact structure, the cost of the raw materials is low, and a foundation is laid for wide application of the recycled concrete.
本发明公开了一种纳米偏高岭土协同作用下的铁尾矿砂再生混凝土及其制备方法。纳米再生混凝土的原料如下重量份数的组分：水泥402～447份，纳米偏高岭土0～45份，天然细骨料320～645份，铁尾矿砂0～323份，天然粗骨料549份，再生粗骨料549份，水190～220份；本发明提升了铁尾矿砂及再生粗骨料的利用率，改善了再生混凝土的力学性能，使再生混凝土具有更致密的结构，并且原材料成本低，为再生混凝土的广泛应用奠定了基础。
