Abstract
Considering the need for developing an alternative construction material, the paper discusses the feasibility of alkali-activated Self-Compacting Geopolymer Concrete (SCGPC). The paper also presents the rheological behavior of fiber-reinforced SCGPC under the effect of steel fibers, dosage of SP and effect of extra water. Fluid-Binder (F/B) ratio of 0.6 with 1% of steel fibers with different dosages of superplasticizer, i.e., Glenium SKY 8630, was considered. The flow characteristics and compressive strength of the samples were studied. The results showed that with 6% and 5% of SP and 5% of extra water content, the mix was satisfying, the flowability properties and the compressive strength were maximum among all other mix proportions.
