Rapid repair concrete prepared from sludge powder of waterworks, and method
The invention relates to the technical field of building materials, and particularly discloses rapid repair concrete prepared from sludge powder of waterworks, and a method. The rapid repair concretecomprises the following components in parts by weight: 318-367 parts of cement, 8-10 parts of nanometer calcium carbonate, 44-51 parts of sludge powder of waterworks, 70-82 parts of a rapid repair agent, 591-607 parts of river sand, 1146-1784 parts of gravel, 6-7 parts of a water reducer and 153-176 parts of water. The rapid repair concrete of the invention has the characteristics of short settingtime, high strength development speed, low raw material cost and high resource utilization.
本发明涉及建筑材料技术领域，具体公开了一种采用自来水厂污泥粉制备的快速修补混凝土及方法，按重量份计，包括以下组分，水泥318～367份，纳米碳酸钙8～10份，自来水厂污泥粉44～51份，快速修补剂70～82份，河砂591～607份，碎石1146～1784份，减水剂6～7份，水153～176份。本发明具有凝结时间较短、强度发展速度较快、原料成本较低和资源化利用较高的特点。
