Abstract:Since 1990, five new methods for testing the potential alkali-reactivity of aggregates have been standardized by AFNOR, the French Bureau of Standards. These methods were all developed out of existing methods such as ASTM C 227 or C 289, CSA A 23.2 14 A, or those proposed by Tamura, Nishibayashi, or Tang Ming Shu. Furthermore, the cement industry has developed a method for testing the stability of a concrete mixture, afterward designated as "concrete test method." All six methods were included in the Recommendations of the French Ministry of Equipment, issued in January 1991, as means for the prevention of damage by alkali-aggregate reaction. The AFREM Working Group on Alkali-Aggregate Reaction started a round robin test on these methods, using the three French reference aggregates. This paper reports the results of this round robin test program, giving comparative data on both the reliability and reproducibility of the five aggregate standard test methods, and showing the good reproducibility of the concrete test method.
