The invention relates to the recycling of waste, in particular to the application of waste residue in aerated brick and the production of aerated brick. In the present invention, high chlorine silica slag slurry is used instead of fly ash to provide strength subsidies after steam curing. At the same time, the use of high chlorine silica slag slurry to replace part of limestone powder can save the amount of limestone or quartz sand. High chlorine silicon slag slurry mainly exists in the form of fine silicon oxide and sodium chloride, the specific surface area up to 300 square 350 per gram, instead of some powder can save after powder dosage, reduce the energy consumption and the cost of grinding process is introduced. By controlling the fluidity of mixed slurry (220 + 10mm) and keeping it in a certain density, the problem of insufficient foaming or collapse caused by too thick or too thin slurry can not be reached. In addition, aluminum powder can be used as foaming agent, and aluminum powder can be combined with K12 (twelve alkyl sodium sulfate) or twelve alkyl sodium sulfonate composite foaming process. The mass fraction of aluminum powder and K12 is 8:2 or 9:1, the uniformity and stability of bubbles are better, and the speed of foaming is controlled more effectively by adjusting the mass fraction. In the present invention, foam stabilizer, such as resin, Arabia gum, bone glue and so on, is introduced to ensure the stability of production quality.

一种添加高氯硅渣浆的加气砖
本专利技术涉及一种废弃物的再利用,特别涉及废渣在加气砖的应用及加气砖的生产上的调整。
技术介绍
加气砖是一种轻质、多孔的新型墙体材料,广泛应用于工业和民用建筑的非承重或围护填充结构。其工艺以钙质材料(生石灰、水泥)、硅质材料(粉煤灰、矿渣粉等)和骨架材料磨细石灰石、石英砂粉为主要原料,掺加发气剂(铝粉、K12),通过配料、搅拌、浇注、稠化、切割和蒸养等过程制成。其结构含有大量均匀而细小的气孔,可以制成不同规格的砌块、板材和保温制品,因其优越的隔音隔热性能受国家大力推广。可见除了工艺的制备方面,原材料的选择对成品的质量影响较大。随着我国对矿产资源的不断开采,资源的缺乏日渐明显,如何利用工业产生的无害废渣逐渐受到建筑行业的关注。
