A recent study published in Scientific Reports delves into the impact of utilizing waste paper aggregate (WPA) and polyethylene terephthalate (PET) on the performance of mortar in construction. The construction industry is increasingly exploring sustainable alternatives to traditional concrete production methods, aiming to reduce the environmental footprint. With urbanization on the rise, the demand for durable and eco-friendly construction materials is growing.
The research focuses on investigating how incorporating waste paper aggregate (WPA) affects various aspects of mortar, including flow time, compressive strength, flexural strength, and thermal conductivity. Additionally, the study explores the potential of polyethylene terephthalate (PET) in enhancing the compressive and flexural strengths of mortars.
By characterizing the materials using advanced analytical tools like EDX spectroscopy and SEM analysis, the researchers were able to conduct a comprehensive analysis of the grain segmentation and microstructural characteristics of the WPA mortars. The study involved testing four distinct mixtures, each with varying percentages of WPA and PET.
The results of the study revealed that mortars incorporating WPA exhibited enhanced compressive and flexural strengths. Specifically, a mixture containing 4% WPA showed a significant increase in both compressive and flexural strength, indicating that WPA can reinforce the mortar and improve its mechanical properties. Furthermore, the inclusion of WPA led to a reduction in thermal conductivity, making the mortars more effective as thermal insulators.
On the other hand, the addition of PET fibers had a contrasting effect on the mortar properties. Mortars containing PET showed a decrease in compressive and flexural strengths, which could be attributed to the hindrance of cement hydration by the smooth surface of PET particles. Despite the challenges in workability posed by WPA, the study underscores the potential of incorporating WPA and PET as sustainable solutions for improving mortar strength and insulation properties.
The research highlights the importance of exploring innovative materials like recycled paper and plastic waste in construction to promote sustainability and reduce environmental impact. By optimizing the use of waste-based materials in mortar formulations, the study contributes to advancing eco-friendly building practices and circular economy initiatives in the construction industry.
