Aerated concrete produced from solid waste and production method thereof
The invention discloses aerated concrete produced by using solid wastes and a production method of the aerated concrete, and belongs to the technical field of aerated concrete. According to the modified foam stabilizer prepared by the invention, surfactant molecules enter interlayer spaces of LDHs through an intercalation effect, so that disordered arrangement of the surfactant molecules is changed into order, the attraction force among water molecules is reduced, and the surfactant molecules and compressed double electric layers of LDHs act simultaneously, so that the surface tension of water is reduced, and bubble coarsening is prevented. The polysaccharide substance and the two surfactants are compounded for use, so that the viscosity can be enhanced, and the bubble coarsening can be delayed. According to the modified foam stabilizer, bubbles are easy to form, round in shape, large in number, small in size and uniform in distribution, and aerated concrete keeps light weight, high strength and good adiabaticity. LDHs can adsorb and fix corrosive ions such as chloride ions, so that the corrosion to aerated concrete is reduced, and the weather resistance and waterproofness of the product are improved. Industrial solid wastes are adopted as raw materials, so that the cost of the raw materials is reduced, and sustainable utilization of resources, energy conservation and emission reduction are realized.
本发明公开了加气混凝土技术领域的一种利用固废生产的加气混凝土及其生产方法。本发明制备了一种改性稳泡剂,其中表面活性剂分子通过插层作用进入LDHs的层间空间,使表面活性剂分子的无序排列变为有序,减少了水分子之间的吸引力,与LDHs的压缩双电层同时作用,降低了水的表面张力,防止气泡粗化。多糖类物质与两种表面活性剂复配使用,能增强粘度,延缓气泡粗化。该改性稳泡剂使气泡形成容易、形状更圆、数量更多、体积更小、分布均匀,使加气混凝土保持轻质、高强度和良好的绝热性。LDHs能吸附并固定氯离子等腐蚀性离子,减少对加气混凝土的腐蚀,提高产品的耐候性和防水性。采用工业固废为原料,降低原料成本,实现了资源的可持续利用和节能减排。
