Abstract:In many situations concrete structures may be exposed to temperatures higher than those assumed as normal environmental conditions. This can be produced by accidental causes, such as fires. In other cases, high temperatures can be generated by the characteristics of the structural application, as in walls, pipes or vessels in some specific industries (nuclear, chemical processing, metallurgy). Most of the knowledge about concrete behavior is based on experimental results obtained on specimens at normal temperatures, which are not representative of the material properties under extreme conditions. In this paper, an extensive analysis of the physical and mechanical properties of normal and high-strength concretes exposed to temperatures up to 700 degrees C is presented. Ultrasonic pulse velocity, static and dynamic modulus of elasticity, and strength and deformations (axial and transversal) under compressive loading were measured. In addition, flexural and splitting tensile strength and the fracture energy were measured. Also, other tests for determining the water permeability, water penetration and absorption were performed on concrete slices with the aim of analyzing the differences in the physical properties of the cover and bulk concrete.
