Abstract

The paper shows an experimental investigation carried out to study the thermal effect on the short-term mechanical properties of concrete. This study presents some experimental results of mechanical-test specimens that were subjected to cold temperatures (-10°C and -20°C), average temperatures (10 and 30°C) and to high temperatures such as 40, 50 and 60°C during 24 hours. Three concrete mixes obtained using different types of aggregates were considered. All the tests for the experimental program have been carried out after cooling of the material. The concrete samples are tested to determine the compressive strengths and modulus elasticity and were then compared with those obtained at room temperature (20°C). The results demonstrated that the performance of concrete considerably falls with the increase of temperature until 60°C. Those results were also completed by scanning the electron microscope observations of the microstructure.
