CONCRETE DETERIORATION DUE TO AGGRESSIVE ENVIRONMENT AND CYCLIC LOADING – THEORETICAL STUDY

Abstract eng:
With the usage of modern cementitious materials, structural elements are designed more slender. For structures subjected to cyclic loadings this means higher stress ranges and thus higher probability of fatigue failure. Structures of transport infrastructure which are mainly exposed to cyclic loading are often located in places of aggressive environment. The paper presents a theoretical study, part of a long-term experimental research focused on the effect of coupled deterioration by aggressive environment and cyclic loading on the concrete specimens. The evaluation of the deteriorative effect of aggressive environment is based on kinetics of chemical reaction between concrete and aggressive solution of hydrochloric acid.
