Abstract: The research on reducing environmental pollution has gradually increased in recent years. At present, the research mostly focuses on the mechanism of geopolymer, but seldom involves alkali aggregate reaction. This study attempts to explore the difference between alkali-activated cementitious material mortar and traditional cement mortar in high temperature and alkali environment. To promote the engineering application of alkali-activated cementitious materials, the deformation behavior of cement mortar with different aggregates and metakaolin geopolymer mortar in high temperature and alkali solution is studied by measuring the length changes of samples at different ages. At the same time, the composition and microstructure of products at different ages are analyzed by XRD, SEM and other micro-methods. It is shown that there are obvious differences in the alkali-aggregate reaction process between geopolymer and cement. There will be no serious alkali aggregate reaction in geopolymer, and aggregates with strong alkali activity can be used in engineering. Geopolymer paste eventually forms zeolite-like structure, which can absorb and solve a large number of harmful alkali and adapt to strong corrosive environment such as marine engineering.

Key words: cement, metakaolin, high temperature and high alkali, alkali aggregate reaction, zeolite structure
