摘要：

Effects of different deformed steel fibers on the preparation and fundamental properties of self-compacting SFRC were experimentally studied. Four types and three volume fractions of steel fiber were considered as the influence parameters. Evaluation method of static segregation resistance of steel fibers is presented using the distribution uniformity of steel fibers in matrix. Several suggestions are proposed to improve the test methods for characterizing workability and to evaluate the efficiency of steel fiber in enhancing strengths of self-compacting SFRC. The predictive models for axial compressive and splitting tensile strengths are proposed in relation with the effective distribution of steel fiber. (C) 2018 Elsevier Ltd. All rights reserved.
