A kinetic based comparison between expansion tests for alkali-aggregate reactivity was
carried out deriving critical rates from test criteria, in an earlier paper. The present paper checks the
assumptions and models of that earlier comparison against results with real aggregates varying in
alkali reactivity. Using the same approach, for each aggregate, expansion rates for three expansion
tests were estimated, corrected for alkalinity and depicted as an Arrhenius plot. The relationship
used data from NF P18-590, ASTM C 1260 and ASTM C 227 expansion test-methods and shows
linear Arrhenius plots for several aggregates, aligned almost parallel to the line obtained for test
criteria. Aspects related to the different experimental conditions on test-methods and their effects
are discussed. The proposed conclusion is that both standards and aggregate results, in the given
conditions, are not inconsistent from the kinetic point of view. Some suggestions are made for
improving the accuracy of the relationship obtained.
