Abstract: 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.

Key words: crack of concrete block wall, temperature crack stress,
