Service life prediction’s algorithm: loading, carbonization, chloride aggression
(BrSTU, 2021)Corrosion reinforcement marine hydraulic structures due to chloride aggression and carbonization of concrete leads to a sharp decrease in the safety of the structure. The steel reinforcement will be subjected to a so-called depassivation process, once the chloride concentration on surface exceeds a ...2021-12-03

Some remarks about chemical prestressing of FRP reinforce-ment
(BrSTU, 2021)In last years has been observed a new wave of interest in the research and practical use of self-stressing concrete, now in combination with various types of non-traditional reinforcement. One of the widely used types of these reinforcements is FRP bars and long fibers (textile). We connect the major ...2021-12-03
