LABORATORY AND FIELD TESTS ON CONCRETE SEALING COMPOUNDS

FIELD AND LABORATORY TESTS TO DETERMINE THE EFFECTS OF CONCRETE CURING COMPOUNDS, CONCRETE SURFACE-SEALING COMPOUNDS ARE DESCRIBED, AND PRODUCTS DESCRIBED AS COMBINED CURING AND SEALING COMPOUNDS ON THE RESISTANCE OF AIR- ENTRAINED AND NON-AIR-ENTRAINED CONCRETE TO FREEZING AND THAWING IN THE PRESENCE OF DE-ICING SALTS ARE DISCUSSED. EMPHASIS IS PLACED ON THE PERFORMANCE OF A BOILED LINSEED OIL-KEROSENE MIXTURE AS A SURFACE SEALER. IT IS CONCLUDED THAT THE PERFORMANCE OF SEALING COMPOUNDS APPLIED TO HARDENED CONCRETE IS NOT IMPRESSIVE, AND IT IS RECOMMENDED THAT THE PRESENT GENERAL PRACTICE OF APPLYING 2 COATS OF LINSEED OIL-KEROSENE SOLUTION TO EXPOSED NEW CONCRETE BRIDGE DECKS AND PAVEMENTS IN ONTARIO BE DISCONTINUED. THE MOST IMPORTANT SINGLE FACTOR IN THE ATTAINMENT OF DURABLE CONCRETE IS THAT THE CONCRETE BE PROPERLY AIR-ENTRAINED. IN THIS RESPECT A VIGOROUS POLICY OF ENSURING THAT CONCRETE IS AIR-ENTRAINED SHOULD BE PURSUED BY PERSONNEL ENGAGED IN CONCRETE QUALITY CONTROL IN HIGHWAY WORK. /AUTHOR/
