摘要

This article investigates the flexural performance of ferrocement panel (FP) reinforced with natural fiber coir (CR) mesh and a hybrid of coir and GI weld (CG) mesh as a substitute to conventional metallic mesh (GI). Six combinations of panel were explored by casting slab panels with dimensions of 1000 mm x 450 mm x 50 mm varying mortar strength and fiber volume fraction. The results indicated the Load carrying capacity of FP made with two layers of CR mesh and CG mesh were comparable when the mortar strength was varied from 22.54 to 26.80 MPa. The ductility index (DI) and toughness index (TI) of CG based FPs was higher than CR based FP by 43 to 108% and 28 to 55% respectively. Improved performance of FP was observed when CG was used as reinforcement. The influence of mortar strength, fiber volume fraction, and aspect ratio of panel on flexural strength of FP was evaluated by identifying a factor \(\:\Phi\) . Linear and regression prediction models were developed for estimation of flexural strength. The models depicted a coefficient of determination ranging from 0.84 to 0.90 with a variation in FS being less than 10%.
