N2 - This research aims to study the effect of temperature on basalt fiber reinforced polymer (BFRP) bars embedded in moist geopolymer concrete. The conditioning temperature varied among 20, 40, and 60°C. The geopolymer concrete was designed with a nominal cylindrical compressive strength of 40 MPa with a slag-to-fly ash mass ratio of 1:3. The samples were conditioned for a duration of 3 months. The tensile strength, moisture uptake, and matrix retention of BFRP bars were measured. Test results highlighted a 30% decrease in the tensile strength, 47% increase in the moisture uptake, and 33% decrease in the matrix retention when the temperature increased from 20 to 40°C. Meanwhile, limited changes to the durability performance of BFRP bars was noted as the conditioning temperature further increased to 60°C.
