Evaluation of concrete structures affected by alkali-silica reaction and delayed ettringite formation
(2012-08)
Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) are expansive reactions that can lead to the premature deterioration of concrete structures. Both have been implicated in the deterioration of numerous ...
Effects of low-level silica fume replacement in ASTM C 1260 and ASTM C 227 mortar-bar testing
(2004-12-18)
Replacement of a percentage of cement by supplementary cementing materials (SCM) can control deleterious alkali-silica reaction. Silica fume, a commonly used SCM, and can be used to mitigate alkali-silica reaction (ASR). ...
Nondestructive evaluation of reinforced concrete structures affected by alkali-silica reaction and delayed ettringite formation
(2011-08)
Alkali-silica reaction (ASR) and delayed ettringite formation (DEF) deterioration have been a problem for the concrete infrastructure in the state of Texas and around the world in recent decades. A great deal of research ...
