Reuse of stone powder formed in the production of manufactured sand is of great significance to environmental protection and resource utilization. In this paper, the waste calcareous rock powder formed in the manufactured sand production line was added into the concrete by 6%, 9%, 12% and 15%, and the total weight of manufactured sand and rock powder was controlled to be constant to prepare C30 and C40 environment-friendly manufactured sand concrete. The influence of rock powder on the compressive strength and transmission performance of concrete was analyzed. It was found that with the increase of stone powder content, the compressive strength of fresh paste and C30 concrete first increased and then decreased, while the concrete transmission performance and the compressive strength of C40 concrete continued to decline. It was suggested that the content of rock powder should not exceed 9%.
