摘要
文中利用微波烧结工艺制备绿色全固废烧结砖,通过对全固废烧结砖进行抗压强度、吸水率以及抗冻性能测试,并借助微观试验手段对烧结砖内部结构进行表征分析.研究发现微波烧结砖性能优于电炉烧结砖.相较于电炉烧结砖体,微波烧结工艺能够促进全固废烧结砖内部的矿物相变,在降低烧成温度的同时提高烧结砖内部结构致密化程度,从而导致微波烧结砖体的抗压强度、吸水率、抗冻性能均得到明显提升.研究可为微波烧结全固废烧结砖在实际的推广提供数据参考.
Abstract
The full solid waste based green sintered brick is prepared by microwave sintering process,and the com-pressive strength,water absorption,and freezing resistance of sintered brick aretested,after which the internal struc-ture of the sintered brick is characterized and analyzed by means of microscopic methods.Compared to electric fur-nace sintered bricks,the microwave sintering process promotes the mineral phase transformation in full-solid waste sintered bricks,which reduces the sintering temperature and improves the internal structure dense degree of sintered bricks,resulting in significantly improved compressive strength,water absorption,and anti-freezing properties of mi-crowave sintered bricks,providing the data reference for the popularization of microwave sintered solid waste sin-tered bricks.
