Effect of Steel Fiber Content on Properties of Fresh Self-compacting Geopolymer Concrete

Abstract

Self-compacting geopolymer concrete (SCGPC) is a cutting-edge sustainable engineering material in construction that eliminates the need for both compaction and Portland cement. In this study, the impact of various steel fiber content on the workability of SCGPC was investigated. The basic workability features of freshly made SCGPC, such as filling ability, passing ability, and segregation resistance, were assessed by employing slump flow, V-funnel, L-box, and J-ring test techniques. Obtained results showed that all the investigated characteristics of SCGPC have retreated due to the inclusion of steel fibers. Findings presented in this research confirmed that the basic requirements of EFNARC could only be satisfied when Vf ≤ 1.0%.
