Abstract: | The Investigation of Demage Monolith Ceiling Slab In recent years the monolith structures are cracked frequently, particularly in concrete walls and reinforced ceiling slab. Usually, the cracks are not the effect of the exterior loads. The reason of that situation lies in the material and in the processes, which occur in concrete during the bond. The paper presents this problem as an example of ceiling slab made of concrete with fly ashes. The large usefulness of nondestructive tests to diagnostics of damaged construction was underlined. |
