    Abstract

    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.
