Abstract

Distress has been observed in the above dam, on its right spillway immediately after its completion in 1957. The distress has been intensified in the eighties with development of thin horizontal cracks in the undersluice barrels, gate gallery and adjoining areas at a level 18m above bed. These have all been chiselled, opened up and epoxy grouted; besides with water proof cement. But parallel cracks opened up soon after. Studies in detail carried out by various government organisations point out that rapid placement of concrete in ’55 - ‘56 leading to thermal stress is the main cause. Though some attribute it to alkali aggregate reaction because of strained quartz in the aggregates. Further studies and remedial measures are under way.

Distress in Hirakud Dam, Orissa, India – Possible Causes and Remedial Measures

St. Louis, Missouri

Distress has been observed in the above dam, on its right spillway immediately after its completion in 1957. The distress has been intensified in the eighties with development of thin horizontal cracks in the undersluice barrels, gate gallery and adjoining areas at a level 18m above bed. These have all been chiselled, opened up and epoxy grouted; besides with water proof cement. But parallel cracks opened up soon after. Studies in detail carried out by various government organisations point out that rapid placement of concrete in ’55 - ‘56 leading to thermal stress is the main cause. Though some attribute it to alkali aggregate reaction because of strained quartz in the aggregates. Further studies and remedial measures are under way.
