Analysis of the porosity of alkali-sensitive aggregates for the assessment of microstructure dependent solubility in the context of ASR

Intensified Alkali-Silica Reaction (ASR) damage has occurred on German roadways in recent years, leading to requirements for compulsory pre-construction investigation of aggregate alkali sensitivity using concrete tests with external alkali supply. However, since these tests are time-consuming and cost-intensive, there is interest in replacing...
