1 A new vision to apply light-weight aggregate composite concretes via development of self-compacting concrete https://www.jourcc.com/index.php/jourcc/article/view/246 https://doi.org/10.61186/jcc.6.4.2 1 This study explores innovative approaches to the application of light-weight aggregate composite concretes through the development of self-compacting concrete (SCC). It highlights the benefits of integrating lightweight aggregates in SCC formulations, which enhance mechanical properties and reduce structural weight. The discussion emphasizes the potential for improved sustainability and efficiency in construction practices, paving the way for future advancements in concrete technology. 1 2 Yousef Aburas Department of Civil Engineering, School of Science and Technology, The University of Georgia, Tbilisi, 0171 Georgia yousefaburas@ug.edu.ge Light-weight aggregate Composite Self-compacting concrete Article.pdf [1] G.
