چکیده
An environmentally friendly building system with suitable properties including durability can be made by using geopolymer concrete and FRP bars. The flexural behavior of geopolymer concrete beams made from Iran mines soil and reinforced with FRP and steel bars was examined in this work. In terms of reinforcement and concrete, the findings of the experimental investigation of geopolymer concrete beams were compared to those of standard cement concrete beams. To accomplish this purpose, a four-point flexural test was performed on 24 specimens of geopolymer and cement concrete beams reinforced with steel, GFRP, and CFRP bars. The initial cracking load, ultimate load, failure modes, number and width of cracks, load-deflection behavior, crack pattern, strain distribution, effective moment of inertia, and ductility were all investigated. The failure modes of tested beams were approximately similar to those predicted by codes, and a comparison of experimental findings with codes predictions reveals that these codes underestimated the beams' flexural strength, but ACI predictions are almost 20% more accurate than CSA ones. Geopolymer beams reinforced with FRP rebars and made with Iran mine soil showed similar results to reinforced cement beams, and the ductility ratio of FRP and steel reinforced geopolymer beams is 5% and 34% greater than that of reinforced OPC concrete, respectively.

تازه های تحقیق
  • Flexural behavior by using a four-point bending test was studied on geopolymer concrete reinforced with FRP bars.
  • ACI predictions are more acceptable than CSA for design the geopolymer beams reinforced with FRP bars.
  • Ductility of geopolymer concrete was more than OPC concrete.
  • The midspan deflection of geopolymer concrete beams was more than the cement concrete beam.
  • The ultimate load-carrying strength of geopolymer concrete was approximately the same as that of cement concrete
  • Geopolymer concrete containing slag had proper adhesion with FRP rebars.
