| Abstract: | Dissolution and geopolymerization mechanism of silicon,aluminum,calcium from alkali activated fly ash were studied.The compressive strength,micro structures,and morphology characteristics of the fly ash geopolymer were also studied.The results showed that during the geopolymerization process,the sphere of fly ash seems to be broken and part of alumino-silicate dissolves,further,the inner of the broken fly ash seems to be filled with large quantity of amorphous geopolymeric products.Calcium participates in g... |
