Waste incineration bottom slag regenerated high-ductility cement-based material and preparation method thereof
The invention discloses a waste incineration bottom slag regenerated high-ductility cement-based material and a preparation method thereof. The high-ductility cement-based material is prepared by mixing and stirring the following raw materials in parts by mass: 200-220 parts of waste incineration bottom slag regenerated micro-powder, 80-110 parts of cement, 100-120 parts of quartz sand, 1.0-1.5 parts of a water reducing agent, 70-90 parts of water and 13-26 parts of polyvinyl alcohol fibers. The regenerated micro-powder is prepared by mixing regenerated micro-powder of a first particle size, regenerated micro-powder of a second particle size and regenerated micro-powder of a third particle size. The preparation method comprises the following steps of: preparing regenerated micro-powder, weighing all the raw materials according to the mass ratio, and uniformly stirring all the raw materials according to a certain adding sequence. The regenerated micro-powder with different particle sizeranges is mixed in proportion, so that the grading of the regenerated micro-powder is improved, the waste incineration bottom slag regenerated micro-powder is used for replacing fly ash, so that theproduction cost is reduced; a dog-bone-shaped test piece prepared from the high-ductility cement-based material has good tensile property.
本发明公开了一种垃圾焚烧底渣再生高延性水泥基材料及制备方法，所述高延性水泥基材料由以下质量份的原料混合拌和而成：垃圾焚烧底渣再生微粉200～220份、水泥80～110份、石英砂100～120份、减水剂1.0～1.5份、水70～90份、聚乙烯醇纤维13～26份，其中再生微粉为第一粒径、第二粒径和第三粒径的再生微粉按比例混合；所述制备方法包括制备再生微粉，按质量比称取各原料配料，按一定的添加顺序将各原料搅拌均匀。本发明将不同粒径范围的再生微粉按比例混合，改善了再生微粉的级配；使用垃圾焚烧底渣再生微粉替代粉煤灰，降低了生产成本；本发明高延性水泥基材料所制备的“狗骨型”试件具有良好的拉伸性能。
