A WORKING HYPOTHESIS FOR FURTHER STUDIES OF FROST RESISTANCE OF CONCRETE

BASIC INFORMATION IS GIVEN ON THE FREEZING OF WATER IN CONCRETE. FROM THIS INFORMATION AND OTHER PUBLISHED MATERIAL, AN EARLY EXPLANATION OF THE MECHANISM OF THE ACTION OF FROST ON CONCRETE WAS DEVELOPED. THE EXPLANATION TAKES INTO ACCOUNT SUCH FACTORS AS THE DEGREE OF SATURATION OF THE CONCRETE, THE PERMEABILITY AND STRENGTH OF THE CONCRETE, HYDRAULIC PRESSURES GENERATED DURING FREEZING, AND AIR-FILLED CAVITIES. IT IS SUGGESTED THAT THE HYPOTHESIS BE MADE THE BASIS OF FURTHER LABORATORY STUDIES OF THE ACTION OF FROST IN CONCRETE. /PCA/
