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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
