This study applied the pull-out test to examine influence of freeze-thaw cycles and hybrid fiber incorporation on bond performance between BFRP bars fiber-reinforced concrete. The bond-slip curves were fitted by existing constitutive model, then strength was predicted a BP neural network. results indicated that failure mode changed from splitting for bar ordinary concrete specimens when exceeded 50, while only occurred all specimens. An increasing trend shown peak slip, but decreasing stiffness increased. could be increased significantly basalt (BF) cellulose (CF) under same freezing thawing conditions as compared without fibers. Malvar model Continuous Curve performed best in fitting ascending descending sections curves, respectively. network also accurately strength, with relative errors strengths ranging 3.75% 13.7%, 86% them being less than 10%.

Abstract This research aimed to evaluate the resistance sodium and magnesium sulfates of geopolymeric mortars, prepared with different proportions alkaline activators silicate hydroxide (Ma), Na2O content in relation metakaolin (MK) silica modulus (Ms). Additionally, an air-entraining additive was also used attempt mitigate expansive effects sulfate attack for 20 weeks. The properties were evaluated by change longitudinal length, mass variation, compressive strength, flexural tensile microstructure. SEM/EDS analyses suggest formation caminite a structure aluminosilicate gel M-A-S-(H) mortars exposed MgSO4, while thenardite indicated as harmful product subjected Na2SO4. experimental results showed that greater amount Na2SiO3 geopolymer formulation contributes denser lower water absorption rate, but resulted physical deterioration expansion after immersion sulfate. did not minimize tensions generated attack. In synthesized Na2O/MK = 15% Ms 1.5 (GEO-15-1.5) 22% 1.0 (GEO-22-1.0 GEO-22-1.5), strengths similar standard samples when immersed Na2SO4 solution increase strength attributed temporary refinement pores crystals.
