耐震性と持続可能性を両立する高強度コンクリート配合を開発。1,000件の配合データを統計解析し、セメント量とCO2排出の強い正の相関を確認。高性能減水剤と長期養生により、セメント量を抑えつつ350MPa以上の強度を実現し、ライフサイクル環境負荷を大幅削減。
English
This study develops a high-performance concrete mix that balances seismic resistance and sustainability. Statistical analysis of 1,000 mix designs reveals a strong positive correlation between cement content and embodied CO2, energy, and resource use. By using superplasticizers and extended curing, the proposed mix achieves compressive strengths over 350 MPa with less than 400 kg/m3 cement, significantly reducing life-cycle environmental impact while meeting seismic code requirements.

📄 Abstract（原文）
Developing high-performance concrete (HPC) that meets seismic resistance requirements and supports sustainable development is one of the most challenging issues in modern building materials science. The concrete mixture proportions were developed, and the optimisation was evaluated through empirical testing using a database of 1,000 concrete mix designs from experiments optimised for compressive strength, ductility, and minimised environmental impact. Each mix has 11 parameters to describe it: cement content, water-to-cement ratio, amount of superplasticiser, amount of coarse aggregate, amount of fine aggregate, curing age, compressive strength, embodied CO₂, energy consumption, and a composite resource consumption index. From the statistical analysis, it can be seen that curing age shows a very strong negative correlation with compressive strength (r = −0.901), while cement content shows a moderate positive correlation (r = +0.229). Nevertheless, the higher the cement content, the greater are the embodied CO₂ (r = +0.987), energy use (r = +0.929), and resource use (r = +0.591), indicating a fundamental performance–sustainability trade-off. A high-quality mix design is employed to achieve compressive strengths of over 350 MPa with less than 400 kg/m³ of cement, using superplasticisers and a longer curing duration. The recommended proportions meet seismic design code requirements for ductility and strength and have been measured to have a significant reduction in life-cycle environmental impact, offering a science-based strategy for earthquake-resistant, net-zero-compliant construction.
