Cement sound absorption material as well as preparation method and application thereof
The invention provides a cement sound absorption material and a preparation method and application thereof, and relates to the field of building construction materials, the cement sound absorption material adopts an alkali excitation technology, uses waste incineration ash, granulated blast furnace slag and fly ash as precursors, and is supplemented with a foaming agent to prepare an environment-friendly porous cement sound absorption material with good sound absorption performance. The waste incineration ash, the granulated blast furnace slag and the fly ash are all industrial byproducts, waste utilization can be effectively achieved, a secondary firing process is not needed, and good carbon emission benefits are achieved. The foaming agent and the waste incineration ash are introduced into the cement sound absorption material, so that the cement sound absorption material has good pore characteristics, namely relatively large porosity and relatively small density. Due to the porous characteristic, the cement sound absorption material has a relatively large sound absorption coefficient. Through an alkali excitation technology, harmful heavy metal elements in the waste incineration ash are solidified in the prepared cement, and the problem of heavy metal ion precipitation is effectively solved.
本申请提供一种水泥吸声材料及其制备方法和应用，涉及建筑施工材料领域，该水泥吸声材料采用碱激发技术，使用垃圾焚烧灰、粒化高炉矿渣和粉煤灰作为前驱体，辅以发泡剂，配制出具有良好吸声性能的环保的多孔水泥吸声材料。垃圾焚烧灰、粒化高炉矿渣和粉煤灰均为工业副产品，可以有效实现废物利用，不需要二次烧制过程，具有良好的碳排放收益。通过在水泥吸声材料中引入发泡剂及垃圾焚烧灰，使得水泥吸声材料具有良好的孔隙特征，即较大的孔隙率和较小的密度。多孔特性使得该水泥吸声材料具有较大的吸声系数。通过碱激发技术，使得垃圾焚烧灰中有害的重金属元素得以固化在所制备的水泥中，有效解决了重金属离子析出的问题。
