Original Abstract

Fire response of concrete structural members is dependent on the thermal, mechanical, and deformation properties of concrete. These properties vary significantly with temperature and also depend on the composition and characteristics of concrete batch mix as well as heating rate and other environmental conditions. This paper presents the effects of a high temperature on selected physical properties of concrete. The main aim of the article is the evaluation of the monitoring concrete properties loaded in a few thermal steps up to 1200 oC. Therefore, the concrete specimens were heated in a programmable laboratory furnace at a heating rate of 5 °C/min. The specimens were loaded at six temperatures, i.e. 200 °C, 400 °C, 600 °C, 800 °C, 1000 °C and 1200 °C were maintained for 60 minutes. The acoustic emission activity and some material characteristics were evaluated in a three-point bending test.
