Paper by ROBERG from ISCR 7th 1994 Vienna Austria
Aggregates were obtained from an alkali-silica damaged concrete road slab aggregates and used for road base concrete with different kinds of cement (low alkali cement, high alkali cement). After analysing the samples produced with these mixes, which were exposed for up to one year to different hardening conditions, no alkali-silika reaction ASR could be stated. But these test results do not allow for drawing general conclusions about the possibility of reusing ASR damaged concrete. However a ASR is unlikely to happen in road bases due to their special characteristics (low cement content, high air voids content) and the addition of low alkali cement.
