本研究は、ブナ材から生成したバイオ炭をモルタルの砂の部分代替材として利用する可能性を検討した。バイオ炭を0〜20重量%添加したモルタルの密度、強度、吸水率などを評価した結果、10%までであれば非構造部材として許容可能な性能を示し、循環型建設への貢献が示唆された。
English
This study investigates the use of beechwood biochar as a partial replacement for sand in mortar. Results show that up to 10 wt.% biochar yields acceptable mechanical performance for non-structural applications, offering lower density and valorization of renewable biomass waste, contributing to circular economy in construction.

📄 Abstract（原文）
The construction sector is responsible for a significant share of global greenhouse gas emissions, while the extraction of natural aggregates is increasingly unsustainable. In this context, biochar, a porous carbon-rich material obtained by biomass pyrolysis, has attracted attention as an eco-friendly additive in cementitious composites. This study investigates the effects of beechwood biochar as a partial replacement for natural sand in mortars. Five mortar series were prepared with biochar contents ranging from 0 to 20 wt.%, while keeping a constant cement mass and adjusting the water content according to the mixture composition. Specimens were tested for density, compressive and flexural strength, pull-off adhesion strength, and capillary water absorption at different curing ages. The results revealed a systematic decrease in density and strength with increasing biochar content, reflecting the low density and high porosity of biochar particles. Nevertheless, mortars with up to 10 wt.% biochar exhibited acceptable mechanical performance for potential application in non-structural elements, while offering benefits in terms of lower density and valorisation of renewable biomass waste. The findings highlight the potential of beechwood biochar as a sustainable partial aggregate replacement, contributing to circular economy strategies in the construction industry.
