    Únavové vlastnosti betonových vzorků vystavených agresivnímu prostředí

  • Original language description

    High stress ranges caused by cyclic loading can result into accelerated crack propagation, higher deflection, structural stiffness reduction and consequently into fatigue failure. Agents contained in the aggressive environment (soluble salts, acids etc.)penetrate into the structure of concrete and reduce its matrix stiffness. The combination of these effects occurs e.g at bridges in urban environment or at crane tracks in chemical plants and leads to higher long-term structural damage. This paper presents current outcomes of long-term experimental programme which main goal is to quantify the combined effect of cyclic loading and aggressive environment on concrete specimens. The specimens are stored in saline lotion and subsequently in hydrochloric acid solution (HCl) for more than five years.
