ALKALI-AGGREGATE REACTION TO NOVA SCOTIA 11. FIELD AND PETROGRAPHIC STUDIES

CERTAIN SILICEOUS AND SEDIMENTARY ROCKS IN NOVA SCOTIA, WHEN USED AS AGGREGATE WITH HIGH ALKALI CEMENT, HAVE PRODUCED EXCESSIVE EXPANSION OF CONCRETE. LABORATORY STUDIES SHOWED A TYPE OF ALKALI-AGGREGATE REACTION TO BE RESPONSIBLE. ROCK TYPES IN STRUCTURES AND IN AGGREGATE SOURCES WERE IDENTIFIED BY PETROGRAPHIC EXAMINATION, THE MAIN TYPES BEING SELECTED FOR STUDY OF ALKALI-REACTIVITY. /AUTHOR/
