Abstract

Since the publication of the last TR30 extensive research has been completed. The key elements of this work were investigations into the relative reactivities of aggregates and aggregate combinations, levels of alkali in the concrete needed to produce a damaging alkali-silica reaction and the effectiveness of pfa and ggbs in minimising risk of damage. This edition now draws on the results of that research and it is now possible to make recommendations that enable more economic and environmentally sustainable use to be made of concreting materials while ensuring that the safety and serviceability of structures constructed to these recommendations are maintained.
