In the heart of Andhra Pradesh, India, a groundbreaking study is challenging conventional norms in the construction industry. Vakula Bharathi Geddam, a researcher from the Department of Civil Engineering at Bonam Venkata Chalamayya Engineering College, is spearheading an investigation that could redefine the way we build our structures. Her research, published in the ‘International Journal of Emerging Research in Engineering, Science, and Management’ (translated as ‘International Journal of Emerging Research in Engineering, Science, and Management’), explores the potential of using Oil Palm Shell (OPS) and Manufactured Sand (M Sand) as partial replacements for traditional aggregates in concrete.
The construction industry has long relied on crushed rocks and river sand as primary aggregates in concrete. However, the escalating demand for these natural resources has led to increased costs and environmental concerns. Geddam’s study aims to address these issues by examining the feasibility of using OPS as a substitute for coarse aggregates and M Sand for fine aggregates in M30 grade concrete.
The research involved a series of tests to evaluate the slump, split tensile strength, compressive strength, and flexural strength of concrete specimens after 7, 14, and 28 days of curing. Concrete samples were prepared with varying proportions of OPS (5%, 10%, and 15%) and M Sand (10%, 20%, and 30%), along with combinations of both. The results were promising, with certain mixtures outperforming conventional concrete.
“The inclusion of OPS and M Sand improved the concrete’s strength properties,” Geddam explained. “This not only reduces construction costs but also promotes environmentally sustainable practices within the construction industry.”
The implications of this research are significant for the energy sector, particularly in regions where oil palm plantations are prevalent. By utilizing OPS, a byproduct of the palm oil industry, construction companies can reduce waste and lower their carbon footprint. Moreover, the use of M Sand, a manufactured alternative to river sand, can alleviate the pressure on natural resources and reduce the environmental impact of construction activities.
Geddam’s findings underscore the potential of OPS and M Sand in boosting the durability and sustainability of concrete structures. As the construction industry continues to seek innovative solutions to enhance performance and sustainability, this research offers a promising avenue for exploration.
“The analysis of these outcomes underscores the factors contributing to the enhanced strength, demonstrating the potential of OPS and M Sand in boosting the durability and sustainability of concrete structures,” Geddam added.
As we look to the future, the adoption of these materials could shape the way we build, paving the way for more sustainable and cost-effective construction practices. This research not only highlights the importance of innovation in the construction industry but also serves as a testament to the power of sustainable practices in driving progress.
