内容記述 | This paper investigated the volume changes of high strength mortars cured in water. The effects of characteristic microstructure on the volume stability were considered in relation to the formation of microcracks. The results indicated that mortars without silica fume exhibited continuous swelling for long ages and the ones with silica fume shrank for a certain period after immersed in water, but started to swell at long ages. Cracking at long ages was confirmed for mortars with and without silica fume. However, there were distinct differences in the characteristics of crack pattern, such as the situation for cracking and their effects on the strength development between both. It was suggested that a mechanism other than autogenous shrinkage was involved in the volume changes that occurred in mortar with an extremely low water/binder ratio. Generation of internal expansive pressure due to the late cement hydration should be taken into account in the mechanism that cause microcracks in mortars at long ages. | |||||
