Full Description
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.
