Córdoba province (Argentina) produces important quantities of aggregates, especially for concrete structures. Low quality materials can decrease structure?s life and increment environmental liabilities and the use of quartz-bearing rocks can develop alkali-silica reactions (ASR) which affect concrete durability. Rocks reactivity from Córdoba was evaluated through standardized methods showing good behaviour due to their favorable textural and microstructural characteristics.
