Factors affecting DEF and ASR in the concrete dam at Vrané nad Vltavou

Original language description

Two degradation mechanisms, delayed ettringite formation (DEF) as well as the alkali-silica reaction (ASR), were investigated in the concrete dam at Vrané nad Vltavou, CZE with an aim to: (1) find those aggregates causing the degradation of the concrete;(2) define those parts of the concrete most affected by the degradation; and (3) correlate the water attack with the extent of degradation. The following methods were used: measurement of residual expansion of the concrete (following the CSN 72 1179 standard), optical microscopy, petrographic image analysis, and scanning electron microscopy combined with energy dispersive spectrometer (SEM/EDS). Eight different sampling points were selected according to the cracks observed on the concrete's surface. DEF was found to be the most important degradation mechanism in the concrete samples; ASR and calcite-rich rims are regarded as minor. Influence of freezing/thawing degradation is also possible. The highest residual expansion was measured o
