Original Abstract
Vývoj modulu pružnosti zmrazovaného mostního betonu pevnostní třídy C 35/45. Sledování relativního dynamického modulu pružnosti pomocí nedestruktivních metod. Zkoušky statického modulu pružnosti v tlaku.
English abstract
This article focuses on structural concrete's (C 35/45) resistance. To evaluate the frost resistance were simultaneously used two methods - ultrasonic impulse method and resonance method. The procedure is based on determination of frost resistance coefficient. A bending tensile strength and a compressive strength have to be tested to achieve data for calculation of the mentioned coefficient. The second process uses non-destructive testing methods (ultrasonic impulse method and resonance method) to observe internal structural damage.
