CONCRETE WITH A HIGH RESISTANCE TO FROST /IN RUSSIAN/

IN SEVERE WEATHER CONDITIONS CONCRETE STRUCTURES SUBJECT TO THE ACTION OF SALT WATER ARE ALSO SUBJECT TO THE AGGRESSIVE ACTION OF FREEZING-THAWING CYCLES AND MARLING. THIS TYPE OF CONCRETE MUST BE OF OF A QUALITY SUPERIOR TO THAT RECOMMENDED BY THE STANDARD GOST 4795-59. ACCORDING TO THE LATTER, THIS CONCRETE CAN BE SUBJECTED TO 300 FREEZING- THAWING CYCLES AFTER 28 DAYS NORMAL HARDENING WITHOUT LOOSING MORE THAN 25 PER CENT OF ITS STRENGTH. METHODS, WHICH CAN BE USED ON CONSTRUCTION SITES AND RESULT IN AN INCREASED RESISTANCE TO FROST, ARE PRESENTED. THREE ADMIXTURES: CALCIUM LIGNOSULPHONATE, A NEUTRALIZED AIR- ENTRAINING RESIN (SNV), AND A STABILIZING INGREDIENT (DK) WERE TESTED ON VARIOUS TYPES OF CONCRETE; TEST RESULTS ARE GIVEN AND COMPARED. /LCPC/RRL/
