“…Collins and Sanjayan [8] compared the workability and equivalent one-day strength of AAS concrete to those of Portland cement concrete at normal curing temperature and reported discrepancies in the mechanical properties like the compressive strength, elastic modulus, flexural strength, drying shrinkage, and creep. Sofi et al [9] considered six inorganic polymer concrete (IPC) mixes to evaluate the effects of the inclusion of coarse aggregates and granulated blast furnace slag. These authors carried out tests and found out that, in most cases, the engineering properties developed by the IPC mixes compared favorably to those predicted by the relevant standards for concrete mixtures.…”

The material properties of cement-zero concrete using alkali-activators have been studied extensively as the latest response to reduce the CO 2 exhaust of the cement industry. However, it is also critical to evaluate the behavior of reinforced concrete beams made of alkali-activated slag (AAS) concrete in terms of flexure and shear to promote the applicability of AAS concrete as structural material. Accordingly, nine types of beam specimens with various ratios of tensile steel and stirrup were fabricated and subject to bending and shear tests. The results show that the flexural and shear behaviors of the reinforced AAS concrete members are practically similar to those made of normal concrete and indicate the applicability of the conventional design code given that the lower density of slag is considered. In addition, a framework using the elastic modulus and stress-strain relation from earlier research is adopted to carry out nonlinear finite element analysis reflecting the material properties of AAS concrete. The numerical results exhibit good agreement with the experimental results and demonstrate the validity of the analytical model.

“…A number of studies have shown that geopolymer concrete has properties making it suitable as a construction material [2][3][4][5]. On the other hand, aside from being innately corrosion resistant, FRP bars are lightweight, electromechanically neutral, and fatigue-and chemical-resistant, as well as having high tensile-strength properties [6][7][8].…”

Geopolymer concrete reinforced with glass-fibre-reinforced polymer (GFRP) bars can provide a construction system with high durability, high sustainability, and adequate strength. Few studies deal with the combined use of these materials, and this has been the key motivation of this undertaking. In this study, the flexural strength and serviceability performance of the geopolymer concrete beams reinforced with GFRP bars were evaluated under a four-point static bending test. The parameters investigated were nominal bar diameter, reinforcement ratio, and anchorage system. Based on the experimental results, the bar diameter had no significant effect on the flexural performance of the beams. Generally, the serviceability performance of a beam is enhanced when the reinforcement ratio increases. The mechanical interlock and friction forces provided by the sand coating was adequate to secure an effective bond between the GFRP bars and the geopolymer concrete. Generally, the ACI 4401.R-06 and CSA S806-12 prediction equations underestimate the beam strength. The bending-moment capacity of the tested beams was higher than that of FRP-reinforced concrete beams from the previous studies.2

“…33 The granulated blast furnace slag was obtained from Holcim (directly from the SRS Saltstone Production Facility (SPF)) and tested both as the sole aluminosilicate powder and as a replacement for portions of the fly ash in geopolymer mixtures. Table 4.14 summarizes the chemistry of the raw materials.…”
