DETERMINATION OF THE RESIDUAL REACTIVITY OF ALKALI SILICA REACTION IN CONCRETE

The present paper discusses the various methods available for the determination of the residual reactivity of concrete structures affected by alkali silica reaction. A combined method has been developed and tested based on fluorescence thin section petrography, scanning electron microscopy with energy dispersive microanalyses and pore solution expression combined with chemical analyses. Practical experience gained from concrete structures is presented, and the applicability of the various methods is discussed. (A) For the covering abstract see IRRD 871351.
