Bonding and toughness properties of PVA fibre reinforced aqueous epoxy resin cement repair mortar
Highlights We use a simple way to obtain well dispersion of PVA fibre & aqueous EP in mortar. We optimise the factor (P/C, W/C, w PVA) for its repair property by ANOM & ANOVA. w PVA has the principal effect on toughness (f b/f c, n i, n f) or bond strength (f AT). We do a confirmatory test to acquire the optimal factor combination for PVA-FPCM.
Abstract Orthogonal experiment with three elements (one of three levels) was employed to optimise the experimental parameters for the repair performances of PVA fibre reinforced aqueous epoxy resin cement mortar (PVA-FPCM) by the analysis of means and variances. The experimental parameters were selected as polymer-cement ratio (P/C), water-cement ratio (W/C), and PVA fibre loading (w PVA) in this paper. Results indicate that, w PVA has the greatest influence on the fracture toughness (flexural/compressive strength ratio f b/f c), the bond strength (f AT), and the impact toughness (the number of repeated impact to the initial crack n i, to the final crack n f). The optimal combination of the process parameters for a high-performance repair mortar through further confirmatory experimental is P/C at 0.20, W/C at 0.35, and w PVA at 1%.
