ABSTRACT
Commencing in the early 1950s, post-independence India witnessed a spurt in developmental activities, which involved construction of various concrete structures. As a result, there is in India a large number of hydraulic structures such as concrete dams and bridges, which are presently more than 50 - 60 years old; well in excess of the age by which problems due to any AAR in concrete should become apparent. A majority of these structures are in satisfactory condition, barring distress due to corrosion of reinforcement in some construction. This led to confidence that the problem of distress due to AAR in concrete may not exist in India.
