A recent study published in ‘Materials Research Express’ has unveiled exciting possibilities for the construction sector by exploring the potential of Abutilon indicum fibres in cement mortar. This eco-friendly approach not only addresses the limitations of traditional cement composites but also opens new avenues for sustainable building materials.
Cement composites are known for their low tensile strength and limited resistance to cracking. However, the incorporation of plant-based fibres like Abutilon indicum has shown promise in enhancing these properties. The research, led by V Aarthipriya from the Division of Structural Engineering at the College of Engineering Guindy, reveals that varying the fibre lengths and contents can significantly improve the mechanical characteristics of cement mortar.
“The flexural and tensile strengths of mortar mixes were significantly improved by the addition of fibres,” Aarthipriya noted, emphasizing the positive impact of these natural reinforcements. The study tested three fibre lengths—5, 10, and 15 mm—combined with varying fibre contents of 0.5, 1.0, 1.5, and 2.0 wt%. The findings indicated that while the tensile properties improved, there was a notable decrease in compressive strength as the fibre dosage and length increased. This reduction is attributed to factors like decreased density and the tendency of fibres to cluster within the mortar.
The research employed a multicriterial decision-making method to determine the optimal mix, which was identified as 5 mm fibre length with a 1% fibre addition. This combination not only provided enhanced mechanical properties but also exhibited strong interfacial bonding between the fibres and the cement matrix. “We recommend using Abutilon indicum fibre in cement mortar for repair and other construction applications,” Aarthipriya added, highlighting the practical implications of the study.
The commercial impact of this research could be substantial. As the construction industry increasingly seeks sustainable materials, the use of natural fibres such as Abutilon indicum could lead to more environmentally friendly building practices. Additionally, this innovation aligns with global trends toward reducing reliance on synthetic materials, potentially lowering costs and enhancing the durability of structures.
As the construction sector continues to evolve, the insights from this study could shape future developments in material science and engineering, paving the way for greener, stronger, and more resilient construction practices.
