摘要
随着社会对资源综合利用,环境效益的关注度越来越高。资源的循环利用成为建筑行业取得持续发展的动力。探究以煤矸石作为粉煤灰页岩砖主要造孔剂的各项性能,得出在一定含量下,不仅降低产品的密度,同时使烧结制品的导热系数大幅度下降,最后获得保温效果好、结构稳定、力学性能良好的烧结多孔砖。
As the development of the society for the comprehensive utilization of resources, the attention of environmen-tal benefits has been highly increasing. Resource recycling has been the force of sustainable development in the constructionindustry. This paper explores the various properties of Shale brick of fly ash with coal gangue as a main pore-former. It isconcluded that under a certain content, it reduces not only the density of the products but also the coefficient of thermal con-ductivity of the sintered products drastically. Finally the sintered porous brick with good heat preservation effect, stable struc-ture and good mechanical properties is obtained.
