Polymer modified jute fibre as reinforcing agent controlling the physical and mechanical characteristics of cement mortar
Highlights Methodology to disperse polymer modified jute fibre homogeneously into the mortar. Significant improvement of CCS, MOR, and FT in jute fibre reinforced mortar. Substantial improvement in TI as well as the PCRE in modified mortar. Plausible mechanism to explain the improvement in mechanical properties.
Abstract Polymer modified alkali treated jute fibre as a reinforcing agent, substantially improves the physical and mechanical properties of cement mortar with a mix design cement:sand:fibre:water::1:3:0.01:0.6. The workability of the mortar is found to increase systematically from 155±5mm (control mortar) to 167±8mm (0.2050% polymer modified mortar). The density of the mortar is increased from 2092kg/m3 to 2136kg/m3 with a concomitant reduction of both water absorption and apparent porosity. Optimal polymer content in emulsion (0.0513%) is found to increase the compressive strength, modulus of rupture and flexural toughness 25%, 28%, 387% respectively as compared to control mortar. Based on the X-ray diffraction and infra-red spectroscopy analyses of the mortar samples a plausible mechanism of the effect of modified jute fibre controlling the physical and mechanical properties of cement mortar has been proposed.
