15 YEARS OF LIVING AT KINGSTON WITH A REACTIVE CARBONATE ROCK

Shortly after a number of highway bridges had been built near Kingston, Ontario, in 1956 and 1957, alkali-carbonate rock reaction was identified as being a cause of concrete deterioration observed in the area. Shortly afterward adjacent concrete structures and pavements were built of concrete aggregate from the same dolomitic limestone formation but selected as being innocuous on the basis of short-term concrete prism expansion tests (expansion using job materials not to exceed 0.02 percent after 84 days' storage at 100 percent relative humidity). Comparing the field performance of concrete in both groups of structure for up to 15 years with the results of short-term, long- term, and accelerated laboratory tests shows that selective quarrying was a successful countermeasure. Whereas the earlier structures now show severe pattern cracking in moisture-prome exposures, those built later are free of blemish.
