Corrosion resistance of steel reinforcement in sulfur concrete depends on its structure density, presence of sulfur compounds in concrete components, humidity of medium. On the basis of potentiostatic investigations and corrosive tests, the following recommendations were made. It is necessary to control the contents of hydrogen sulfide, organic impurities and acids (recalculated for sulfuric acid),...
In the case of concrete failure, destruction or strain caused by transverse displacement the formation and propagation of scratches are controlled by the stress intensity factor KIIC, characterizing the state of stress at the top of the scratch. The paper presents an analysis of the results of experiments concerning the stress intensity factor KIIC for lightweight (keramsite concrete) and heavy (dense)...
