The crack in concrete block wall is a new problem for the new wall
materials. At First, based on engineering investigations, causes and
positions of cracks in concrete block wall are studied, and temperature crack
and dry shrink crack are two main kinds of cracks. Secondly, the temperature
crack stress is calculated by temperature difference in an existing building.
Thirdly, the mechanism of dry shrink crack is expounded by Kelvin-equation and
the dry shrink crack stress are also analyzed. In the end, causes of
cracks in concrete block wall are explained.
