Abstract: Lightweight concrete (LWC) has garnered considerable attention in recent years due to its advantageous properties such as reduced density, improved thermal insulation, and enhanced sustainability. This review paper provides a comprehensive overview of the advancements, properties, production methods, applications, and future prospects of lightweight concrete. It covers various types of lightweight aggregates, admixtures, and innovative techniques employed in the production of lightweight concrete. Furthermore, it discusses the mechanical, thermal, and durability properties of LWC and compares them with conventional concrete. The review also explores the wide range of applications of lightweight concrete in construction projects and its contribution to sustainable development goals. Finally, it identifies current challenges and future research directions in the field of lightweight concrete.
