Polymer modified jute fibre as reinforcing agent controlling the physical and mechanical characteristics of cement mortar

A brief review on the chemical modifications of lignocellulosic fibers for durable engineering composites

“…These could be ensured by effective modifications either to the chemical composition or to the surface properties of jute fiber by some chemical treatment. In this context, modification of both the chemical composition as well as surface properties of jute fiber by mild alkali and combined dilute alkali and polymer emulsion were done and reported elsewhere [102][103][104].…”

Hydrogen-rich water revealed benefits in controlling the physical and mechanical performances of cement mortar

“…Interestingly, the water absorption and apparent porosity of the mortar samples reduces significantly beyond the 0.4 ppm hydrogen concentration. Usually, the lesser porosity may lead to achieving a higher bulk density and lower water absorption capacity of cement mortar [33,34]. In this study, the higher concentration of hydrogen-rich water possesses a lesser apparent porosity, which in turn leads to increase the bulk densities and reduces the water absorption capacity of the mortar samples.…”

“…The flexural test according to ASTM C348 [32] was performed using a loading rate 2.6 kN/min. The modulus of rupture (MOR) and the flexural modulus of the control, as well as the hydrogen-rich water based cement mortar, was measured from the three-point bending test [33]. At least ten samples from each batch of the mortar samples were tested to obtain an average compressive as well as flexural strength.…”

Impact of leaf fibre modification methods on compatibility between leaf fibres and cement-based materials

“…The problem of plant fibres and cement compatibility has always been a difficult problem in the process of research and utilisation plant fibres at home and abroad. The poor compatibility [22][23][24] of plant fibres and cement is mainly due to following factors: first, anti-coagulant effect of dissolved substances (called extracts) of plant fibres on cement hydration; second, presence of a large number of hydroxyl groups in the cell walls of plant fibres with high water absorption, resulting in an adverse effect on the physical and mechanical properties of fibre cement-based materials; third, alkaline attack in cement hydrates can significantly reduce the strength and durability of plant fibres.…”
