Ecological reinforcement of cementitious mortars with jute fibres: Effects on mechanical performance

Résumé

In recent years, there has been considerable interest in the use of plant fibers in the construction sector. These fibers can represent an alternative to traditional fibers used in building materials, such as polypropylene fibers. Sustainable development requires materials that are environmentally friendly, i.e., natural and recyclable. Therefore, the aim of this article was to examine the mechanical performance (compressive and flexural strength) and properties of cementitious mortars reinforced with small-scale jute fibers. The jute fibers used in this work were pre-treated with demineralized water and cut into small sizes with a maximum length of 5 mm to eliminate the use of superplasticizers to make the mix homogeneous. The results obtained showed that mortars reinforced with 0.5% plant fibers had higher tensile and compressive strength than ordinary mortars. Furthermore, whatever the percentage, the fibers retained the interior temperature during cool periods, which could help reduce the power consumption of home air-conditioning systems. Therefore, the introduction of fibers saves cement, admixture, and water for each percentage. These results point to a promising future for the use of plant fibers in cementitious materials.
