ALKALI-SILICA REACTION IN A LIGHTWEIGHT CONCRETE BRIDGE
The case study of the Belgian bridge B51 seems to be interesting because of two remarkable exceptions. Firstly, the studied construction attacked by an ASR is a lightweight concrete bridge. Secondly, the bridge deck had to be replaced as a consequence of the suffered damage. The results of mineralogical and chemical investigations point to a possible influence of the lightweight aggregate as a source of alkalines. It is not clear why the extra porosity of the lightweight concrete could not compensate the expansive effect of the ASR gel production. (A) For the covering abstract see IRRD 871351.
