The paper deals with the damage of the concrete surface by defreezing chemical agents. The first part of research is oriented to composition, design of concrete and test of fresh (slump test, bulk density of fresh concrete) and hardened concrete (compressive strength, bulk density of hardened concrete). The second part is oriented to test of concrete surface resistance against the effect of defreezing chemical substances. Two protective coatings were used. Tests were performed on samples without coating and on sam...
