Alkali-silica reaction (ASR) expansion: Pessimum effect versus scale effect

摘要: The effect of aggregate size on ASR expansions has been largely studied and conflicting results exist concerning the that leads to highest expansion. Most research works clearly show a pessimum However, all available in literature were obtained using different experimental conditions combined effects other important parameters, such as specimen used expansion tests, have often neglected. This paper aims investigate Experimental highlight scale effect, combination appears be influenced by reactive silica content aggregate. Modelling at microscopic level is propose quantification this effect.
