Low-Carbon Cementitious Materials with 100% Solid Wastes

This book presents an innovative paradigm for synthesizing low-carbon cementitious materials through 100% utilization of industrial solid wastes, incorporating calcium sulphoaluminate and dicalcium silicate, which simultaneously addresses the dual challenges of bulk solid waste disposal and CO₂ emission reduction in conventional cement production. The subject of this book is civil engineering material and industrial solid waste management. The research systematically explores the phase reconstruction mechanisms of multi-component solid wastes under controlled calcination conditions, hydration behavior evolution across curing ages with characterization of reaction products and pore structure development, and AC impedance spectroscopy-based hydration monitoring enhanced by ARIMA modeling. It further investigates the regulatory effects of desulfurization gypsum on hydration kinetics and microstructure, seawater-activated hydration pathways yielding hardened pastes with compressive strength, and machine learning-driven performance prediction. Engineering applications are demonstrated through optimized grouting materials exhibiting tailored flowability and interfacial bonding strength, concrete formulations with early-age strength development, and impact-resistant composites capable of absorbing energy. Environmental validation via life-cycle assessment confirms reduced resource and CO₂ emissions, establishing a comprehensive framework for sustainable cementitious material development from waste valorization to engineered applications. Given its scope, the book is a valuable reference book for research students and reference resources for researchers, academics, and industrial scientists working in the field of civil engineering material and industrial solid waste management.
