Small concrete hollow blocks have been widely used in a large number of residential buildings in Shanghai, but due to various reasons, cracks in block buildings have become more prominent. Combined with the experience of the design work of concrete small hollow blocks in Shanghai, the causes, types and related control measures of some common cracks in small concrete hollow block buildings were fully described. Through the continuous improvement of design, production and construction, many block constructions have been in good use so far, and cracks in block construction have gradually been solved.
