摘要
地聚物对焚烧飞灰中的重金属具有良好的固定作用.为了进一步探索固化飞灰后的地聚物固化体的抗环境侵蚀性能,开展了固化体高温—恒温时间—地聚物抗压强度的研究及经受高温后固化体的重金属浸出试验,探讨抗压强度与高温、恒温时间之间的关系以及地聚物固化垃圾焚烧飞灰的稳定性.通过对固化体试块的高温试验以及对不同温度、不同恒温时间下固化体抗压强度试验,分析这三者之间的关系,建立数学模型,并根据实验结果拟合温度—恒温时间—抗压强度的三维曲面.
Geopolymers can effectively immobilize the heavy metals in the municipal solid waste incineration fly ash.In order to further explore the environment corrosion resistance of fly ash geopolymer,high temperature test of geopolymer is presented,referring to the relationship between high-temperature,constant temperature and compressive strength.Through the compressive strength test of geopolymer test cubes at different temperature and different constant temperature time,the coupling relationship among temperature,constant temperature time and compressive strength of geopolymer is analyzed,and the mathematical models of these is established.Additionally the leaching concentractions of heavy metals in the fly ash-geopolymers after heating are determined to examine the stability.Based on the results of test,the 3D curved surface of temperature,constant temperature time and compressive strength of geopolymer is fitted.
