Experimental Study of GFRP-Reinforced Geopolymer Concrete Columns under Different Loading Conditions

This study discusses the behavior of ambient-cured circular geopolymer concrete specimens tested under different loading conditions. Twelve specimens were cast and tested to investigate the influence of the type of the reinforcement, that is, steel and glass fiber-reinforced polymer (GFRP), the pitch of the transverse reinforcement, and loading conditions (concentric axial load, 15 and 35 mm eccentric load, and four-point bending). The axial...
