Bio-Based Concrete Enhancement for Sustainable Construction

Year: 2025

Type: article

Abstract: The construction industry significantly contributes to carbon emissions and resource depletion, necessitating innovative approaches for sustainable concrete production. This study explores bio-based enhancements, focusing on Microbial Induced Calcite Precipitation (MICP) and Algae-Based CO₂ Sequestration to improve concrete's structural performance and environmental sustainability. MICP utilizes bacteria (Sporosarcina pasteurii) to induce calcite precipitation, enhancing self-healing properties and strength. Algae-based admixtures and biochar offer a natural solution for CO₂ absorption during curing, reducing the carbon footprint. The proposed bio-based concrete solutions are evaluated based on strength, durability, permeability, and sustainability metrics. Experimental validation demonstrates that these enhancements improve mechanical properties, reduce environmental impact, and promote long-term durability compared to conventional concrete. This study contributes to green construction practices by integrating biological systems with modern materials for eco-friendly and resilient infrastructure.
