Simple coloured dye field test to detect Alkali Silica Reaction (ASR).

Field Test to identify Alkali Silica Reaction (ASR) in concrete. Two reagents are applied to the broken surface of a concrete core and the excess rinsed off. On contaminated concrete, the resultant stains reveal the presence of ASR. The stains also reveal the extent of the ASR in the concrete and indicate the stage of ASR progression. Yellow indicates that degradation has begun; pink warns that degradation is advancing.
