Systematic Review on Reinforcing Mortars with Natural Fibers: Challenges of Environment-Friendly Option

ABSTRACT

In recent years, research has been carried out to examine natural fibers reinforced construction mortars (NFRM), which are now increasingly replacing synthetic fibers reinforced mortars, with a view to producing construction materials that not only limit environmental impacts but also improve their mechanical properties and thermal insulation characteristics. This article reports on research conducted using natural fibers for mortar reinforcement, through a systematic review of publications, based on a bibliometric analysis extracted from the Web of Sciences (WOS) and Scopus databases. In addition, analysis of the treatment of natural fibers used in the mortar reinforcement is also presented. In this context, the analysis of physical and thermal resistance parameters reveals a considerable increase in annual publications on this research topic while the literature using treated fibers represents nearly 12% of the NFRMs literature. Moreover, the results indicate the fiber treatment improves adhesion in the mortar matrix systems of composite materials obtained. It causes their capacity for water absorption to increase and their thermal conductivity to decrease, thus contributing to heat absorption and, above all, to their durability. It is desirable that this bibliometric analysis is susceptible to inform researchers in order to conduct further research to advance this field.

摘要

近年来,研究人员对天然纤维增强建筑砂浆(NFRM)进行了检测,该砂浆正在逐渐取代合成纤维增强砂浆,以期生产出既能限制环境影响,又能改善其机械性能和隔热性能的建筑材料. 本文通过对出版物的系统审查,基于从科学网(WOS)和斯科普斯数据库中提取的文献计量分析,报告了使用天然纤维进行砂浆加固的研究. 此外,还对砂浆加固中使用的天然纤维的处理进行了分析. 在这种情况下,对物理和热阻参数的分析显示,关于这一研究主题的年度出版物大幅增加,而使用处理过的纤维的文献占NFRMs文献的近12%. 此外,结果表明,纤维处理改善了所获得复合材料的砂浆基体系统中的附着力. 它会导致它们的吸水能力增加,导热系数降低,从而有助于吸收热量,尤其是提高它们的耐久性. 这是可取的,这种文献计量分析容易通知研究人员,以便进行进一步的研究,以推进这一领域.
