Experimental Study of Measurements Techniques of Residual Properties of Concrete Subjected to High Temperature
Original language description
Elevated temperatures caused by fire initiate changes of mechanical and physical characteristics of concrete (HAGER, 2013). The paper is aimed to determination of the sensitivity of testing techniques used for evaluation of the actual condition of the concrete structures applied to the structure damaged by fire. The slabs 1300x2300x150 mm of ordinary hardened concrete (except this to be tested in the virgin conditions) were heated to elevated temperature according to standard temperature-time curve (EN 1991-1-2) up to required temperature (for each slab 300, 500, 700 a 900 °C) and rested at the nominal temperature for sixty minutes. After heating process and gently cooling down to the ambient temperature were produced testing specimens (core samples, cubes and prisms) from each slab. The concrete specimens were tested by using of standard testing approaches to determine mechanical characteristics (e.g. compressive and tensile strength). Degradation of the mechanical parameters were determined by perce
