Application of One-Cycle Freeze Tests for the Evaluation of Frost Resistance of Concrete

Source

An automatic device for observing deformation of 100 by 100 by 400 mm concrete specimens during the freezing cycle was developed. By computer processing the dilation factor R is evaluated and deformations are registered and plotted graphically. The value of R is, according to Vuorinen, the difference between the relative length change of the specimen over the temperature range of -20 to 0°C and the relative change over the temperature range of 0 to -20°C. The dimension is μm/m 20°C. The results of the one-cycle test are compared with the test results of concrete resistance to rapid freezing and thawing for various kinds of air-entrained and nonair-entrained concretes.
