RESISTANCE OF CONCRETE SURFACES TO SCALING ACTION OF ICE-REMOVAL AGENTS

THIS REPORT IS A RESUME TO DATE OF INVESTIGATIONS CONDUCTED TO TEST MATERIALS AND PROCEDURES FOR PROTECTING CONCRETE PAVEMENTS AGAINST SCALING AND DISINTEGRATION CAUSED BY CALCIUM CHLORIDE AND OTHER THAWING AGENTS USED FOR ICE REMOVAL. A LABORATORY INVESTIGATION BY THE BUREAU OF PUBLIC ROADS WAS STARTED IN 1948 ON METHODS OF PROTECTING THE WEARING SURFACE OF CONCRETE AGAINST THE ACTION OF CALCIUM CHLORIDE. LATER A SIMILAR STUDY WAS MADE OF THE EFFECT OF OUTDOOR WEATHER CONDITIONS ON SMALL SLABS ON THE GROUND. IT WAS FOUND THAT RESISTANCE TO SCALING IS AFFECTED BY AIR CONTENT, TYPE OF AIR-ENTRAINING ADMIXTURE, SURFACE TREATMENTS OR COATS, ADMIXTURES OF OILS, INHIBITORS, FLYASH AS A REPLACEMNT FOR PORTLAND CEMENT, RATE OF APPLICATION OF CALCIUM CHLORIDE, CURING METHODS, THAWING AGENTS OTHER THAN CALCIUM CHLORIDE OR COMMON SALT AND BY THE VACUUM METHOD OF PLACING CONCRETE. /AUTHOR/
