FROST HARDENING OF CONCRETE WITH CHEMICAL ADMIXTURES /IN RUSSIAN/

A PRESENTATION IS MADE OF THE RESULTS OBTAINED FROM THE ADDITION OF SODIUM CHLORIDE, POTASSIUM CHLORIDE, CALCIUM CHLORIDE, IRON CHLORIDE, SODIUM NITRATE, POTASSIUM CARBONTE AND CALCIUM NITRATE TO CONCRETE ACCORDING TO THE QUANTITY OF ADMIXTURE, CURING TEMPERATURE AND CEMENT COMPOSITION. CONCRETE REACTIONS DURING SETTING AND HARDENING ARE DESCRIBED. A TABLE SHOWS CONCRETE STRENGTH OBTAINED AFTER THE ADDITION OF RECOMMENDED OPTIMUM QUANTITIES OF SODIUM CHLORIDE AND CALCIUM CHLORIDE, SODIUM NITRATE, AND POTASSIUM CARBONATE IN RELATION TO THE FREEZING TEMPERATURE (DOWN TO -25 DEGREES C). TO PREVENT RAPID SETTING CAUSED BY THE ABOVE ADMIXTURES, IT IS POSSIBLE TO ADD RELATIVELY LARGE QUANTITIES OF CALCIUM LIGNOSULPHONATE (UP TO 2 PERCENT BY WEIGHT OF CEMENT) TO THE MIXTURE. /LCPC/RRL/
