Modified recycled aggregate concrete with granite waste residue powder cooperating with silica fume and preparation method of modified recycled aggregate concrete
The invention discloses modified recycled aggregate concrete with granite waste residue powder cooperating with silica fume and a preparation method of the modified recycled aggregate concrete. The modified recycled aggregate concrete is prepared from the following raw materials in parts by weight: 26 to 38 parts of granite waste residue powder, 7 to 13 parts of silica fume, 167 to 195 parts of cement, 474 to 595 parts of recycled concrete coarse aggregate, 291 to 375 parts of fine aggregate, 78 to 102 parts of water and 1.89 to 2.13 parts of a water reducing agent, wherein the water-cement ratio is 0.37 to 0.45. Industrial and building solid waste is utilized in all components, the utilization rate is high, environmental protection is achieved, and resources are saved. Compared with traditional recycled aggregate concrete, the strength of the prepared modified recycled aggregate concrete is obviously improved, and meanwhile, the durability, workability and other properties of the modified recycled aggregate concrete are improved. In addition, part of the properties of the modified recycled aggregate concrete exceed those of common concrete.
本发明公开了一种花岗岩废渣粉协同硅灰的改性再生骨料混凝土及其制备方法。花岗岩废渣粉协同硅灰的改性再生骨料混凝土由如下重量份数的原料组成：花岗岩废渣粉26～38份、硅灰7～13份、水泥167～195份、再生混凝土粗骨料474～595份、细骨料291～375份、水78～102份、减水剂1.89～2.13份，水灰比为0.37～0.45。本发明全组分利用工业及建筑固体废弃物，利用率高，绿色环保，节约资源。制备的改性再生骨料混凝土相对于传统再生骨料混凝土，强度得到明显提升，同时改善了其耐久性、和易性等性能，此外，其部分性能超出普通混凝土。
