Title: LEARNING TO LIVE WITH A REACTIVE CARBONATE ROCK
Accession Number: 00217427
Record Type: Component
Abstract: FACED WITH BUILDING A FOUR-LANE CONCRETE HIGHWAY FOR 30 MILES WEST OF KINGSTON, ONT., WHERE THE LOCAL DOLOMITIC- LIMESTONE AGGREGATES MIGHT SHOW EXPANSIVE REACTIVITY IN CONCRETE IN THE PRESENCE OF ALKALI, AN INVESTIGATION WAS MADE TO DETERMINE THE SAFEST AND MOST ECONOMICAL WAY OF DOING THIS. SELECTION OF AGGREGATES PROVED POSSIBLE ON THE BASIS THAT THEY SHOWED LITTLE EXPANSION IN CONCRETE PRISMS MADE WITH HIGH ALKALI CEMENT AND CURED UNDER STANDARD CONDITIONS. CONFIRMATORY DATA WERE OBTAINED IN THE LABORATORY ON THE FACTORS THAT INFLUENCE THE DEGREE OF EXPANSION AND THE EFFECT OF ALKALIES FROM A SOURCE OTHER THAN THE CEMENT. ALSO DESCRIBED ARE PRECAUTIONS TAKEN TO INSURE THAT ONLY NON- REACTIVE AGGREGATES WERE USED AND THAT THE OTHER FACTORS FACTORS FAVORING EXPANSION WERE MINIMIZED. /AUTHOR/
