Microstructural insights and technical challenges of effectively adopting high-volume GGBS in blended cements for low-carbon construction
Zengliang Yue, Xiaohong Zhu
Abstract
High-volume blended slag cements (HVBSC), with over 70% GGBS replacement, offer a promising route to reduce clinker use and utilise industrial by-products. This review examines HVBSC hydration mechanisms, reaction products (C-(A)-S-H, LDH), strength development, and durability challenges. Strategies to enhance early-age performance are discussed, alongside the need for multiphysics modelling. A conceptual framework is proposed to guide HVBSC development and scaling in suitable regional contexts.
