Aerated concrete block cured by cement kiln tail flue gas and preparation method of aerated concrete block
The invention discloses an aerated concrete block cured by cement kiln tail flue gas and a preparation method of the aerated concrete block, and belongs to the technical field of concrete materials. The aerated concrete block comprises 20-30 parts of a carbon sequestration cementing material, 30-40 parts of dry sand, 1-5 parts of heavy calcium powder, 0-5 parts of dihydrate gypsum and 35-45 parts of water. The preparation method comprises the following steps: batching, stirring and pouring, standing, cutting and curing. The method is scientific and reasonable in design and convenient to use, the carbon sequestration cementing material is adopted for preparing the aerated concrete, the cement kiln tail flue gas is utilized for curing the aerated concrete, alkaline minerals in the aerated concrete can be promoted to rapidly react with acid gas in the flue gas, the hydration-heat sealing-acidification ternary reaction of an aerated concrete blank is achieved, and the product quality is improved. Therefore, the strength of the aerated concrete is quickly improved, and energy conservation and emission reduction are really realized.
本发明公开了利用水泥窑尾烟气养护的加气混凝土砌块及其制备方法，属于混凝土材料技术领域。所述加气混凝土砌块包括20～30份的固碳胶凝材料、30～40份的干砂、1～5份的重钙粉、0～5份的二水石膏和35～45份的水，所述制备方法包括配料、搅拌浇筑、静停、切割和养护。本发明设计科学合理，使用方便，采用固碳胶凝材料制备加气混凝土、利用水泥窑尾烟气养护加气混凝土，促使加气混凝土中的碱性矿物可快速与烟气中酸性气体反应，实现加气混凝土坯体水化‑热合‑酸化三元反应，以此快速提高加气混凝土强度，真正实现节能减排。
