METHOD FOR ACCELERATED ESTIMATION OF FROST RESISTANCE OF CONCRETE

A method for accelerated estimation of frost resistance of concrete comprises testing samples by freezing and thawing in 5 % solution of sodium chloride at the temperature of - 50 5°C. Frost resistance is determined according to linear equation, taking into consideration change after 5 cycles of tes...

Beschreibung
Zusammenfassung:	A method for accelerated estimation of frost resistance of concrete comprises testing samples by freezing and thawing in 5 % solution of sodium chloride at the temperature of - 50 5°C. Frost resistance is determined according to linear equation, taking into consideration change after 5 cycles of tests of ratio of total lengths of process cracks on side faces of sample, which reveal in the solutionof tonin to the area of side face of sample.
