摘　　要：通过实验对粉煤灰地聚物的力学性能及水化产物成分进行了研究,得出了最佳制备工艺参数,并利用FTIR和DTA/TG表征手段对不同龄期粉煤灰地聚物的凝胶体作了分析,表明在水化过程中粉煤灰内玻璃体发生了解聚—缩聚反应,主要形成N-A-S-H产物。Through the test,it studied the mechanical properties of fly ash geopolymer composition and hydration products,obtained the optimal process parameters,and used FTIR and DTA/TG characterization tools to analyze the gel of fly ash geopolymer at different ages.Results showed that： vitreous within the fly ash occurred about poly-condensation reaction in the hydration process,and mainly formed N-A-S-H products.
