Biochar Aerated Calamus Rotang Block (BAC Block)

This study investigates the incorporation of biochar as a cement replacement along with calamus rotang into Autoclaved Aerated Concrete (AAC) blocks. Through a comparative analysis with traditional red bricks and AAC blocks, the project highlights the environmental benefits of BAC (Biochar Aerated Calamus Rotang) blocks, particularly their potential to reduce carbon emissions in the construction industry. A series of experimental studies evaluated the compressive strength, water absorption, density and dry shrinkage test. The results revealed that 1.5% replacement of cement by biochar along with addition of extra 1% calamus rotang shows at most similar properties and value of an AAC block. Thus the findings underscore the importance of exploring alternative materials like BAC blocks to address environmental challenges and promote greener building solutions. Overall, the study advocates for the adoption of BAC blocks as a viable and sustainable option for construction projects, aligning with global efforts toward sustainable development and environmental conservation in the built environment.
