All-solid-waste anticorrosive concrete and preparation method thereof
The invention discloses all-solid-waste anticorrosive concrete and a preparation method thereof, and belongs to the technical field of concrete. The all-solid-waste anticorrosive concrete is prepared from the following components in dosage: 510 to 620kg/m < 3 > of solid waste micro powder, 650 to 720kg/m < 3 > of tailing sand, 800 to 990kg/m < 3 > of solid waste aggregate, 40 to 70kg/m < 3 > of an exciting agent, 10 to 16kg/m < 3 > of a high-efficiency water reducing agent, 6 to 10kg/m < 3 > of a trisiloxane compound and 15 to 21kg/m < 3 > of a preservative, wherein the water-cement ratio control range is 0.38 to 0.42. The gelling material and the coarse and fine aggregate of the all-solid-waste anticorrosive concrete are all composed of industrial solid wastes, a large number of natural mineral raw materials are saved, mining and damage to mines are reduced, toxic and harmful ions of the absorbed solid wastes are solidified in the concrete, no harm is caused to the environment, stockpiling of the solid wastes is reduced, and the cost is reduced. The solid wastes are recycled as resources, so that the method has the characteristics of high utilization rate of the solid wastes and excellent mechanical property and corrosion resistance.
本发明公开了一种全固废防腐混凝土及其制备方法，属于混凝土技术领域。全固废防腐混凝土的原料包括如下用量的组分：固废微粉510～620kg/m3、尾矿砂650～720kg/m3、固废骨料800～990kg/m3、激发剂40～70kg/m3、高效减水剂10～16kg/m3、三硅氧烷类化合物6～10kg/m3、防腐剂15～21kg/m3，水灰比控制范围为0.38～0.42。全固废防腐混凝土的胶凝材料和粗细骨料全部由工业固体废弃物组成，节省了大量天然矿物质原料，减少对矿山的开采和破坏，同时消纳的固体废弃物有毒有害离子固化在混凝土中，对环境无危害，减少了固体废弃物的堆存，将固体废弃物作为资源进行再利用，具有固体废弃物利用率高、力学性能及防腐蚀性能优异的特点。
