Highlights ASR potential of granites with a similar chemical composition is investigated. The same image analysis parameters can be applied to granites of different mineralogy. Expansion of mortar-bar in AMBT is correlated with content of reactive minerals. Proposed automatic IA is an effective preselection of granites for durable concrete.
Abstract The alkali-silica reactivity of granites may significantly affect the durability of road and airfield concrete pavements. The aim of the study was to evaluate the reactivity of granites commonly used as an aggregate in concrete pavements, with particular emphasis on microscopic methods. The research was focused on petrographic diagnosis of reactive minerals in granites, their quantitative analysis and comparison of the obtained results with standard measurements. The strained quartz was recognized as a reactive component and the linear relationship between its content and specimens expansion was found.
