INFLUENCE OF THE COOLING RATE ON THE RESULTS OF TESTS ON CONCRETE FOR FROST AND DE-ICING SALT-RESISTANCE

DER EINFLUSS DER ADKUEHLGESCHWINDIGKEIT AUF DAS ERGEBNIS DER PRUEFUNG VON BETON AUF FROST-TAUSALZ-BESTAENDIGKEIT

If the frost and de-icing salt test is carried out with a 3% common salt (sodium chloride) solution, as specified in Austrian standard b3306, then the result is not influenced by the rate of cooling. This applies if an air temperature of -18 degrees C at approximately 10 cm from the test sample is achieved in the low temperature cooling test after five hours maximum, and the cooling test has a circulation of air. Where test methods are used which do not comply with Austrian standard b3306 (salt spreading on a frozen water film), the reproducibility of the technique is worse and/or the accurate determination of the failure or damage stages is more difficult.
