Quantitative Analyses on Interactions of Mix Proportion Factors Influencing Mechanical Parameters of Steel Fiber Reinforced Concrete

Abstract

For the purpose with apllying steel fiber reinforced concrete (SFRC) to structural components, it is an important subject to establish and connect each other designs of mix proportion, material characteristics and component section, respectively for good workability, necessary mechanical properties and required component performance of SFRC. In this paper, in order to establish a material design of SFRC, experimental investigations were conducted by compression, tension and fracture toughness testings for a sines of SFRC specimens with manufactured under various mix proportions. From the experimental results, quantitative analyses were performed concerning interactions among aspect ratio of steel fiber, fiber volume fraction and cement-water ratio on mechanical parameters of SFRC.
