With increasing attention on the reduction of CO2 emissions, the sustainability of construction materials has become one of the most growing issues in concrete science and engineering research fields. New sustainable construction materials, such as alkali-activated materials, calcium sulfoaluminate (CSA) cement, and limestone calcined clay cement (LC3), have been suggested and high-performance and/or highly durable construction materials using special admixtures, such as nanomaterials, have been studied to reduce the environmental impact during the life cycle of construction materials.This Special Issue aims to highlight and share recent findings in developing new sustainable cementitious materials, modeling their hydration kinetics, investigating their microstructure, improving the performance and durability of cementitious materials using functional supplementary ingredients, suggesting novel test methods for new construction materials, etc. In this Special Issue are presented the following areas:Sustainable concrete and alternative binders
Hydration kinetics of sustainable cementitious materials
Characterization of sustainable cementitious materials
Re-utilization of industrial by-products for construction materials
High strength and durable cementitious materials
Property enhancement by functional additives
Energy storage through construction materials.
