High-strength mineralized aerated building block prepared from solid waste and preparation method of high-strength mineralized aerated building block
The invention discloses a high-strength mineralized aerated building block prepared from solid waste, and the mineralized aerated building block is prepared by adding water into basic materials comprising calcium solid waste, silicon-aluminum solid waste and a foaming agent, the building block is in contact with gas containing carbon dioxide to generate mineralization reaction, heat generated by the mineralization reaction is controlled by adjusting a building block formula and a mineralization process, so that a system reaches the temperature at which water in the building block can be evaporated into water vapor to generate hydrothermal reaction under the condition of no external heat source and water vapor, and the strength of the mineralized aerated building block is improved. According to the invention, calcium solid waste and silicon-aluminum solid waste are adopted as main raw materials, water is added to prepare the building block, and the building block releases heat in the process of mineralization reaction with carbon dioxide to raise the temperature of the system; through regulation and control of a building block formula and a mineralization process, the system reaches the temperature at which water in the building block can be evaporated into water vapor under the condition of no external heat source, so that the building block is subjected to hydrothermal reaction under the condition of no external water vapor, and the strength mineralization of the aerated building block is improved.
本发明公开了一种固废制备的高强度矿化加气砌块，矿化加气砌块采用包括钙质固废、硅铝质固废和发泡剂的基础材料，加水制成砌块；砌块与含二氧化碳气体接触发生矿化反应，通过砌块配方及矿化工艺的调整控制矿化反应产生的热量，使体系在无外加热源和水蒸气的情况下达到可使砌块内的水蒸发为水蒸气从而发生水热反应的温度，提高矿化加气砌块的强度。本发明采用钙质固废、硅铝质固废为主要原料，加水制成砌块，砌块在与二氧化碳接触发生矿化反应的过程中放出热量使体系温度升高，通过砌块配方及矿化工艺的调控使体系在无外加热源的情况下达到可使砌块内水分蒸发为水蒸气的温度，从而使砌块在无外加水蒸气的情况下发生水热反应，提升加气砌块强度矿化。
