Vliv vybraných technologických činitelů na odolnost silničního betonu proti CHRL

Abstract

This bachelor thesis focuses on the differences in the properties of concrete surfaces using different treatment methods. These differences are evaluated by means of tests on fabricated samples. The first part of the thesis summarizes the domestic knowledge related to the testing of resistance to water and chemical deicing agents, the specification of concretes in XF environment, the theory of aerated concretes and then the actual determination of the resistance of concrete surfaces to water and chemical deicing agents. Individual tests for fresh and hardened concrete are also discussed. In the second part, the aim will be to develop test fixtures for testing various surfaces for resistance to CHRL by Method A. Another objective will also be to establish the basic tests for both fresh and hardened concrete. The thesis will conclude with an evaluation and comparison of the whole experiment and a summary of all the findings of the concrete resistance test against CHRL.
