Study on Compressive Strength Characteristics and Aging of Flow Value for Geopolymer Mortar Using of Fly Ash as Active Filler

In this study, compressive strength characteristics and aging of flow value of geopolymer mortar using fly ash were experimentally examined.As a result, following knowledge was obtained.(1) Compressive strength increases using finely ground fly ash and high concentration aqueous sodium metasilicate solution.( 2) Aging of flow value and compressive strength tend to be different depending on Concentration of sodium metasilicate aqueous solution, presence or absence of fine grinding of fly ash, and addition ratio of setting retarder.Moreover, it was hypothesized that state of floc formation is different depending on presence or absence of fine grinding of fly ash.Then, it was shown that it is necessary to verify influence on unit quantity of sodium metasilicate aqueous solution, aging of flow value, and compressive strength characteristics.
