Závislost odolnosti betonu na parametrech vzduchu v čerstvém a ztvrdlém betonu

Abstract

This Diploma Thesis deals with comparison between properties of fresh and hardened concrete. The comparison is related to parameters obtained from measurement with Air Void Analyzer and to the parameters determined according to the standard ČSN EN 206-1 (Change Nr.1). The main aim of this work is determination of the dependence of freeze thaw resistance of concrete on its air parameters in fresh and hardened state. Some chapters of the thesis describe the methods for testing of resistance of hardened concrete. The comparison of results and recommendations are given in conclusion.
