Performance of bamboo biochar as partial cement replacement in mortar
Pyrolysis under limited oxygen conditions at high temperatures is used to produce bamboo biochar. The construction industry often utilizes cement, which is a significant contributor to greenhouse gas emissions and environmental damage. To decrease the use of cement, this study examines the effective...

| description | Pyrolysis under limited oxygen conditions at high temperatures is used to produce bamboo biochar. The construction industry often utilizes cement, which is a significant contributor to greenhouse gas emissions and environmental damage. To decrease the use of cement, this study examines the effectiveness of bamboo biochar as a partial cement replacement in mortar. The study determines the optimal percentages of bamboo biochar as a partial replacement and evaluates its mechanical performance in terms of compressive and flexural strength. The percentages tested include a smaller range of 0.5%, 1%, 1.5%, and 2%, and a higher range of 5%, 10%, 15%, and 20%. The samples are cured for 7, 14, and 28 days. The study concludes that 10% is the optimal percentage replacement for compressive strength, while 5% is optimal for flexural strength. Additionally, the study finds that according to ASTM C618-19, bamboo biochar is best classified as a filler rather than a pozzolan, as it does not meet the class N-pozzolan requirement. |
