Durability, creep, shrinkage and transport processes in concrete

The paper deals with a research project, which was initiated to verify actual effects of creep and shrinkage of concrete (both normal-weight and light-weight aggregate concrete) on composite structures. For this reason, two nearly identical steel-concrete composite testing beams were prepared, varying only in the type of the used concrete. This paper describes the tests realized on the beam using normal-weight concrete. To ensure clear representation of results, a specimen with a steel basic beam is used, but the principles are valuable also for other types of similar structures, for example concrete-concrete composite structures.
