High-Volume Mineral Admixtures in Cementitious Binders: Towards Carbon-Neutral Construction delivers an overview of the broad applications of high-volume supplementary cementitious materials (SCMs) in cementitious binders, addressing the most promising ways to use them to reduce carbon emissions in the construction and building industry. This book focuses on the applications and scientific challenges of high-volume SCMs blends, elaborating on the possibilities as well as offering original perspectives on using different kinds of blended cements in the manufacturing process. Emphasis is placed on activity estimation and quality assessment, the properties of high-volume SCM-blends at both the fresh and hardened stages, self-hydraulic properties, and potential use as the sole binder, as well as associated environmental impacts and carbon footprint reduction.

Xiaohong Zhu

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.
