EFFECT OF CALCIUM CHLORIDE ON THE STRENGTH DEVELOPMENT OF CONCRETE STORED AT LOW TEMPERATURES

CONCRETE CYLINDERS, 6 BY 12 IN. IN SIZE, MADE AT 70 F, WERE STORED IN ROOMS MAINTAINED AT VARIOUS TEMPERATURES BETWEEN 20 AND 40 F UNTIL 1 DAY BEFORE TESTING IN COMPRESSION. THE SPECIMENS WERE PLACED IN AIR AT 70 F AND THE STEEL MOLDS WERE REMOVED 1 DAY BEFORE TESTING. THE CONCRETES CONTAINED 0, 2, 3 OR 4 PERCENT OF CALCIUM CHORIDE BY WEIGHT OF CEMENT. ADDITIONS OF CALCIUM CHLORIDE INCREASED THE STRENGTHS AT ALL AGES WITH EACH STORAGE TEMPERATURE; THE INCREASES WERE MOST MARKED AT AGES LESS THAN 7 DAYS AND TEMPERATURES OF 32 F AND LOWER. EXCEPT FOR AGES LESS THAN 3 DAYS OR STORAGE TEMPERATURES LOWER THAN 32 F THE INCREASES IN STRENGTH WERE ABOUT THE SAME WITH THE 2 PERCENT AS WITH THE 4 PERCENT ADDITIONS OF CALCIUM CHLORIDE. /AUTHOR/
