Measurement of linear thermal expansion coefficient of concrete at high temperatures: A comparison of isothermal and non-isothermal method

Original language description

The linear thermal expansion coefficient, ?(T), of several types of concrete is determined in the temperature range of 20-800 °C using two different methods, namely, the isothermal and linear heating methods. The coefficient ?(T) is in general evaluatedas the temperature derivative of the thermal strain which is measured by a push-rod dilatometer. The pros and cons of the two methods are found to be complementary. While in the isothermal heating method sample temperatures are well established, the linear heating method is much less time demanding and provides a large number of experimental data. The latter is important for a proper evaluation of ?(T) as a derivative of the thermal strain as well as for the ability to observe processes that take placein samples as the temperature is changed.
