PROBLEM TO BE SOLVED: To provide a geopolymer composition capable of improving durability. ! SOLUTION: There is provided a geopolymer composition which comprises: an active filler including at least one selected from fly ash, blast furnace slag, incinerated sewage sludge and kaolin; silica or a silica compound; and an alkali solution, in which the molar ratio between the silica content and the alkali content contained in the solution is set at 0.50 or less. In addition, the molar ratio between the alkali content contained in the solution and the content of water is preferably set at 0.075 or more. Further, in the active filler, the content x of a calcium compound preferably satisfies the following expression: 0<x≤30(vol%). ! COPYRIGHT: (C)2015,JPO&INPIT |
