Analytical study about the expansion progress of concrete exposed to combined alkali silica reactions and freezing thawing cycles

Using numerical simulations, this study investigated the concrete expansion damage caused by the coupled action of freeze-thaw cycles (FTC) and alkali silica reactions (ASR). In the authors’ previous experiments, it was shown that a preceding ASR definitely accelerated the succeeding expansion by FTC. Further, even if the specimens have...

Alkali silica reaction in the afsluitdijk: Assessment of concrete damage and remaining service life using experimental and modelling research

Alkali Silica Reaction (ASR) is one of the degradation mechanisms in concrete that poses a threat to the service life of existing structures. This physio-chemical process is progressive and can affect the the strength, stiffness and stability of concrete structures. A lot of mitigation measures are available to prevent the deleterious effects of...
