SUSCEPTIBILITY OF VARIOUS UK AGGREGATES TO ALKALI-AGGREGATE REACTION

Abstract

A group of lithologically varied UK aggregates have been incorporated into concrete prisms of variable alkali content to ascertain the alkali levels at which significant AAR first occurs. Petrographical analysis has been carried out on these prisms to identify the cause of the expansion and microcracking observed. (A) For the covering abstract see IRRD 871351.
