Guide to Diagnosis and Appraisal of AAR Damage to Concrete in Structures Part 1 Diagnosis (AAR 6.1) /

This book describes procedures and methodologies used predominantly to obtain a diagnosis of damaged concrete possibly caused by Alkali-Aggregate Reaction (AAR). It has two primary objectives, namely firstly to identify the presence of AAR reaction, and whether or not the reaction is the primary or...
