abstract = "The ageing of metakaolin-based geopolymer of special composition (1.2K 2O·Al2O3·4.2SiO 2· 14H2O) has been studied by flexural force measurements, a molybdate analytical method and Fourier transform infrared spectroscopy (FTIR). The results enable new insight into details of the structural development responsible for early strength development between 25 h and 100 h and the unfavorable weakening for ageing above 200 h. In particular the increase in strength is related to the slow development of an aluminosilicate network enclosing preformed polysilicate chains. A fast condensation of silicate chains occurs during the dissolution of metakaolin in the first 25 h of the ageing process. The subsequent destruction of polymeric silicate chains finally causes the weakening.",
