In response to the urgent need for achieving carbon neutrality in the construction industry, with Biochar-Based Cement and Concrete for Sustainable Construction, an international group of experts has set out to provide a timely, comprehensive overview of biochar. Although the method is relatively new, extensive research has been conducted in recent years to systematically gather information proving biochar as an ideal medium for carbon sequestration when used as an engineered additive in cementitious materials, but also to strengthen concrete in all key dimensions via enhancements to hydration and integration into the hardened matrix.

The volume pragmatically stands out as an invaluable resource which offers up-to-date guidance on eco-efficient construction materials’ manufacturing and practical application examples backed by considerations regarding their environmental soundness. At the same time, it stimulates research into future developments with relevance to interdisciplinary audiences both in academia and industry.

Über Autor(innen)

Zhu, Xiaohong
Dr. Zhu is currently the EBI-Shell fellow at the Department of Civil and Environmental Engineering, University of California, Berkeley. He received his PhD from the University of Leeds with a thesis on the topic of morphological and structural changes of C-S-H. He has rich experience in the study of cementitious materials and published more than 50 papers in the Top Journals in this field. In the Ph.D. thesis, he explained the root causes for the morphological changes of C-A-S-H gel in the presence of high-volume supplementary cementitious materials (SCMs) at the atomic level. With the experimental observations from SS NMR and TEM-EDX, the structural-dependent nature of C-A-S-H gel in blended cements is revealed. He will take the tenured academic position at the Beijing University of Technology at the end of 2024.
