Identifying Concrete Cracks from Appearance

Dear reader we have discussed many aspects of cracks in concrete. Plastic shrinkage cracks micro cracks, cracks due to alkali silica reaction, cracks due to yielding of reinforcement and other cracking agent, crack and corrosion friendly environment were discussed. Here we will show cracks in structural members. Here we will include cracks beam and column.
