The construction industry significantly contributes to global carbon emissions, creating an urgent need for sustainable and carbon-negative building materials. Biochar, a carbon-rich byproduct derived from the pyrolysis of agricultural biomass, has emerged as a potential additive that can both improve material performance and sequester atmospheric carbon. This research investigates the incorporation of biochar into conventional brick and plaster compositions to assess its environmental and structural viability. A novel carbon-channeling experimental setup was developed to simulate real-world exposure conditions using exhaust gases. Mechanical testing, including compressive strength, density evaluation, and water absorption analysis, was performed in parallel with CHNS elemental testing to determine carbon retention capabilities. Through detailed performance evaluation and statistical interpretation, this study aims to optimize the mix proportions of biochar-enhanced materials for eco-friendly construction, providing a sustainable alternative that aligns with climate change mitigation goals.
