Preparation method of composite material, composite material and application of composite material
The invention particularly relates to a preparation method of a composite material, the composite material and application of the composite material, and belongs to the technical field of desulfurization by-product recycling. The preparation method of the composite material comprises the following steps: obtaining a flue gas semi-dry desulfurization byproduct; steel slag is obtained; the method comprises the following steps: under the condition of a preset environment temperature, crushing and mixing the flue gas semi-dry desulfurization by-product and steel slag to obtain a premix; and performing hot braising on the premix to obtain the composite material. According to the method, secondary utilization of the semi-dry flue gas desulfurization by-products can be achieved, steel slag and the semi-dry flue gas desulfurization by-products are co-doped, the steel slag is hydrated to produce hydroxyl ions, the hydroxyl ions are utilized to excite depolymerization of vitreous bodies of the semi-dry flue gas desulfurization by-products, the hydration reaction of a mixture is promoted, the hydration products are bonded with one another, and the secondary utilization of the semi-dry flue gas desulfurization by-products is achieved. The composite material with high compactness and durability is obtained, and the strength of the composite material exceeds that of common concrete.
本发明特别涉及一种复合材料的制备方法、复合材料及其应用，属于脱硫副产物再利用技术领域。一种复合材料的制备方法，包括如下步骤：得到烟气半干法脱硫副产物；得到钢渣；于预设环境温度的条件下，将烟气半干法脱硫副产物与钢渣破碎并混合，得到预混物；将预混物经热焖，得到复合材料。其能够实现烟气半干法脱硫副产物的二次利用，通过将钢渣与烟气半干法脱硫副产物复掺，使钢渣水化产出氢氧根离子，利用氢氧根离子激发烟气半干法脱硫副产物玻璃体解聚，促进混合物的水化反应，使水化产物相互胶连，得到密实度和耐久性均较高的复合材料，该复合材料强度超过普通混凝土。
