A STUDY OF THE FROST DAMAGE OF CONCRETE: 1-FREEZING OF WATER AND SOLUTIONS OF DIFFERENT SURFACE ACTIVE AGENTS

THE MODE OF FREEZING OF DISTILLED WATER, AND OF SOLUTIONS OF NEUTRALIZED VINSOL RESIN, TEEPOL, AND SODIUM HYDROXIDE IN GLASS TUBES HAS BEEN STUDIED IN THE HOPE OF FINDING SOME EXPLANATION TO THE PROBLEM OF THE VARYING PERFORMANCE OF CONCRETE CONTAINING DIFFERENT AIR-ENTRAINING AGENTS DURING THE FREEZ-THAW CYCLES. THE RESULTS INDICATE THAT THE ADDITION OF CERTAIN SURFACE ACTIVE AGENTS PRODUCES A NOTICEABLE REDUCTION IN THE BOND STRENGTHS AMONG THE INDIVIDUAL ICE CRYSTALS, AND BETWEEN THE ICE CRYSTALS AND THE SURROUNDING VESSEL. THIS LOWERING OF BOND STRENGTH CAN BE SUFFICIENT TO CHANGE COMPLETELY THE MODE OF FREEZING FROM DISRUPTIVE TO NON-DISRUPTIVE. A SIMILAR ARGUMENT MAY BE APPLIED TO THE FREEZING OF CONCRETE BLOCKS, AND IT IS CONSIDERED TO BE MORE ACCEPTABLE THAN THE CURRENT IDEAS WHICH RELY ON THE PRESENCE OF AIR BUBBLES INCORPORATED IN THE CONCRETE BULK.
