THE MECHANISM OF FROST ACTION IN CONCRETE

MUCH OF THE RESEARCH FOR THIS REPORT WAS CARRIED OUT AT NAPERVILLE FARM, THE PORTLAND CEMENT ASSOCIATIONS OUTDOOR EXPOSURE PLOT FOR CONCRETE TEST SPECIMENS. SECTIONS ARE INCLUDED ON FROST ACTION, GENERATION OF HYDRAULIC PRESSURE IN ROCKS, FREEZING IN CEMENT PASTE AND THE EFFECT OF DE- ICERS. IT IS CONCLUDED THAT THE PERFORMANCE IN A SEVERE CLIMATE OF CONCRETE OUT-OF-DOORS IN CONTACT WITH THE GROUND DOES NOT DEPEND UPON THE CHARACTERISTICS OF THE CONCRETE ALONE. UNDER SOME CIRCUMSTANCES CONCRETE REMAINS IMMUNE TO DAMAGE BY FROST. FROM THE RELATIVE BEHAVIOUR OF DIFFERENT CONCRETES UNDER ONE SET OF CONDITIONS, IT IS NOT POSSIBLE TO PREDICT ACCURATELY THE RELATIVE BEHAVIOUR UNDER DIFFERENT CIRCUMSTANCES. /RRL/
