Influence of Environmental Conditions on Temperature and Relative Humidity in Concrete Specimens

Abstract

In order to understand the basic parameters that cause the frost damage of concrete in a natural environment, exposure experiments of concrete specimens were conducted. Concrete specimens with two different water-cement ratios were exposed in a natural en-vironment with or without sheltering by a roof protection, and the variation of tem-perature and relative humidity inside the specimens were measured. Based on analyses of the measured data, several useful results were obtained and discussed.
