摘要:
The potentiality on alkali activation of volcanic tuff with calcium-based materials, fly ash, and their mixtures as additives were comprehensively investigated in this study. Several characterization strategies have been employed for mechanism exploration. CaO and fly ash (FA) brought about more dramatic responses than CaSO4 and alkaline activator on activating the volcanic tuff-based geopolymer, which was relatively stable under the wetdry alternated conditions. The symmetrical stretching vibration of SieOeT (T = Al or Si) was right-shifted to the band at approximately 1036 cm(-1), implying t...
