Abstract

Properties of self-compacting fiber-reinforced geopolymer concrete (SCFRGC) are investigated in this paper. The effects of two types of steel fiber namely corrugated and hooked-end with different fiber volume fractions (Vf) are conducted on both fresh and hardened properties. The used Vf of steel fiber were 0, 0.5, 1 and 2% with aspect ratio 37.5 for both types. Slump flow, V- funnel and L-box were conducted to assess the fresh properties of the tested concrete mixes. Whereas, compressive strength, splitting tensile strength, flexural strength as well as toughness indices were studied in hardened state. The study proved that the production of SCFRGC can be achieved using local materials. Moreover, the evaluated fresh properties slightly decreased with adding steel fibers to geopolymer concrete (GC) mixes. On the other hand, the mechanical properties including compressive, splitting tensile and flexural strengths improved due to steel fiber addition, and the improvements increased with increasing Vf. Hooked-end steel fibers showed the best improvements with 2% Vf as the enhancements of 61.5%, 106% and 76% were obtained for compressive, splitting tensile and flexural strengths, respectively. Moreover, using steel fibers to reinforce GC to produce SCFRGC showed greatly enhancement in the toughness indices. The improvements increased by increasing Vf.
