CASE HISTORIES OF POOR CONCRETE DURABILITY IN ONTARIO HIGHWAY STRUCTURES

THE PURPOSE IS TO EXAMINE THE FACETS OF THE ROLE (USUALLY DETRIMENTAL) THAT WATER HAS PLAYED IN THE PERFORMANCE OF HIGHWAY STRUCTURES IN ONTARIO BY DOCUMENTING INVESTIGATIONS OF PERFORMANCE. IN EACH CASE CAREFULLY PLANNED INVESTIGATIONS ARE CITED. CASE HISTORIES ARE INCLUDED OF BRIDGE PIERS WITH SEVERE EXPOSURE, THE EFFECT OF DE-ICING SALTS ON BRIDGE DECKS, ALKALI-CARBONATE REACTIONS, FAILURES IN GOOD QUALITY CONCRETE DUE TO FREEZING OF CONFINED WATER, AND FAILURES INVOLVING WATER IN WHICH EXPOSURE PLAYED LITTLE PART. IN EACH CASE THE ACTION TAKEN AND RECOMMENDATIONS MADE TO PRECLUDE FUTURE SIMILAR BEHAVIOR ARE DISCUSSED. /CGRA/
