Based on the crack widths of normal sections of recycled concrete beams under short term loading, the similarities and differences between normal concrete and recycled concrete were compared.It was focused on the crack developing mechanism and width influencing factors of recycled concrete crack.The expression of flexural crack width of recycled concrete beams was presented based on the bond-slip theory and the experiments result.The results showed that the recycled aggregate replacing rate was the extraessential factor of recycled concrete crack, and high discreteness was the main features.The calculation precision of the crack width formula was proved sufficient to meet the demand of design by the test results.
