建筑垃圾基轻质材料的制备及在海绵城市建设中应用探讨

摘要

Construction of sponge city,construction waste resource utilization have been widely concerned in society.Using geopolymer produced by slag and sodium silicate reaction as cementing materials,construction waste as padding,water polyacrylate and PP fiber as strengthening and toughening phase,through H2O2 chemistry foaming and room temperature and ordinary pressure curing,light-weight thermal insulation materials system can be prepared.Probably application field of construction waste based light-weight materials in construction of sponge city (green roof especially) is summarized,for the guidance of practical application.%“海绵城市”建设,建筑垃圾资源化利用,已成为当今社会广泛关注的问题.利用矿渣、水玻璃反应产生地聚合物为胶凝材料,以建筑垃圾为填料,以水性聚丙烯酸树脂和PP纤维为增强、增韧相,通过H2O2化学发泡和常温、常压养护,制备出轻质保温材料系统探讨建筑垃圾基轻质材料的制备及在“海绵城市”,尤其是“绿色屋顶”建设中可能应用,为将来实际应用提供参考.
