Title Of Article :
Alterations in concrete samples due to Alkali–Carbonate–Reaction ‘ACR’
Abstract :
The Alkali-Aggregate-Reaction pathology (AAR) over time destroys concrete constructions in the civil engineering field, because of an expansive solid gel that leads to interstitial pressure until cracking and checking-cracks.This article shows a six-month search for the ACR effects on concrete samples (A) control and (B, C) affected by ACR . Damage symptoms were observed microscopically, chemically and physicomechanically. Significant results have been analyzed in ACR concrete such as: discoloration, aureole, swelling, chemical components, etc.
