Practical measurement for steel fiber distribution of the SFRC beams

摘要

This paper introduces practical measurement of steel fiber distribution in steel fiber reinforced concrete (SFRC) which serves as the matrix of prestressed SFRC beams. Using digital image processing in mesos-copical mechanism of SFRC, "the Dynamic System of Measuring Steel Fiber Distribution" is developed. Compared with theoretical analysis, the system is practical and valid, and a new method is provided for guiding production technology of SFRC and controlling constructional quality.
