Abstract
In this paper,taking an office building as an example,the concrete strength,protective layer thickness and carbonization depth of each component of the existing building are tested and analyzed.The results show that the surface of the concrete members is exposed to rein-forcement and pockmarked surface,but there is no insufficient force of the members,uneven settlement of the foundation and concrete crack-ing.The beam,column,plate and other components of the project are in normal working condition.The average concrete strength of cast-in-place column,cast-in-place beam and cast-in-place slab is 27.9,28.8 and 30.2 MPa,respectively.The average thickness of concrete rein-forcement protective layer is17.8～33.3 mm;The average carbonization depth of concrete is 1.18～3.2 mm.The coefficient of variation of the test data of compressive strength of all components,thickness of protective layer of reinforcement and carbonization depth of concrete is small,which confirms the reasonable reliability of the test data.关键词
