Potential of Using Pyrochar And Biochar In Civil Engineering Application

Abstract

The growing emphasis on sustainable and low-carbon construction practices has led to increased interest in alternative materials that can enhance the performance and environmental footprint of civil engineering projects. This study explores the potential use of biochar and pyrochar, carbon-rich byproducts derived from biomass pyrolysis, in various civil engineering applications. Both materials exhibit favourable properties such as high porosity, large surface area, and chemical stability, making them suitable for incorporation into construction materials. The research investigates the physical, chemical, and microstructural characteristics of biochar and pyrochar using techniques such as X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The effects of incorporating these materials into cementitious matrices are examined in terms of compressive strength, durability, and carbon sequestration potential. Results indicate that controlled addition of biochar and pyrochar can improve specific properties of concrete and soil while also contributing to carbon capture and waste valorisation. The findings support the viability of using these materials as sustainable additives in civil engineering, paving the way for further research into their long-term performance and environmental benefits.
