In a significant step towards sustainable construction, researchers have explored the potential of utilizing eggshell powder as a green alternative to traditional cement in mortar. The study, led by Kechkar Chiraz from University 8 May 1945, highlights how recycling waste materials not only conserves natural resources but also addresses the pressing issue of waste management. With eggs being a staple food source, the sheer volume of eggshells generated presents an opportunity for innovative recycling.
Chiraz’s research, published in ‘Medžiagotyra’ (Material Science), reveals that incorporating eggshell powder—rich in calcium carbonate—can enhance the mechanical properties of mortar. The study tested various substitution rates of eggshell powder, finding that a 10% replacement improved workability and increased compressive strength by approximately 10%. Furthermore, the flexural tensile strength saw an impressive boost of around 20%. These enhancements suggest that the construction sector could benefit significantly from integrating this waste material into building practices.
“Using eggshells not only reduces the carbon footprint associated with cement production but also transforms a common waste into a valuable resource,” Chiraz remarked. This sentiment underscores the dual advantage of sustainability and economic efficiency, appealing to construction companies eager to adopt greener practices.
The findings also indicate that the mortar produced with eggshell powder exhibited reduced density and greater durability, with lower porosity and water absorption rates. However, it is essential to note that while the mortar showed improved performance in several areas, its resistance to sulfuric acid was diminished. This aspect highlights the need for further research to balance the benefits and limitations of using eggshell powder in construction materials.
As the construction industry grapples with the challenges of sustainability and resource depletion, the implications of this research could be far-reaching. The potential for integrating waste materials like eggshells into mainstream construction could not only lower production costs but also contribute to a circular economy where waste is viewed as a resource.
The study invites construction professionals to rethink their material choices, paving the way for innovative solutions that align with environmental goals. As the industry moves towards more sustainable practices, the utilization of eggshell powder could represent a pivotal shift, marking a step forward in the quest for eco-friendly construction methods.
