Abstract
The development of compressive strength of alkali activated metakaolin in dependence or waterglass to metakaolin ratios and quartz additions were investigated during ageing at room temperature. The compressive strength could be optimized for maximal strength for nominal Si/Al ratios of about 1.8-2 of the binder for ageing between 7 and 10 days. However this composition invariably leads to weakening for longer ageing time (weakening effect). Moreover, the optimum in strength for Si/Al ≈ 1.9 could be seen as a shoulder or weaker peak in an extended field of Si/Al and alkali/Al ratios. Additions of quartz, either as "sand" for mortars or as fine grained quartz or as significant virgin contents in the kaolin source could avoid the weakening effect and improve, therefore, the geopolymer property.
