The rapid growth of urban centres , particularly in S E Asia, has b ht b t l i i i ith brought about a looming crisis with reinforced concrete structures

Concrete surface failure – man made Concrete surface failure - natural Concrete failure due to environment Concrete failure due to corrosion of steel
