Micro-expansive cement-based material as well as preparation method and application thereof
The invention discloses a micro-expansive cement-based material as well as a preparation method and application thereof, and belongs to the technical field of building materials. The micro-expansive cement-based material is prepared from the following raw materials in percentage by mass: 5-20% of desulfurized fly ash and 80-95% of clinker. The micro-expansive cement-based material is prepared by utilizing the expansion effect provided by the generation of ettringite in the desulfurization ash hydration process, and the prepared material has better expansion performance and compression resistance. The preparation process is simple, the cost is low, and the problem that a large amount of flue gas desulfurization ash is accumulated in the semi-dry sintering process is solved.
本发明公开了一种微膨胀水泥基材料、其制备方法及应用，属于建筑材料技术领域。本发明的微膨胀水泥基材料，按质量分数由如下原料组成：脱硫灰5～20％，熟料80～95％。本发明利用脱硫灰水化过程中钙矾石的生成所提供的膨胀效果，来制备微膨胀水泥基材料，所制备的材料具有较好的膨胀性能和抗压性能。本发明的制备工艺简单，成本低廉，而且还解决了半干法烧结烟气脱硫灰大量堆积的问题。
