The usage of lightweight concrete has a significant importance in contemporary architecture dues to its ability to reduce structural load, higher thermal performances and unlocks methods to innovative design ideas. Perlite, vermiculite, and expanded clay are examples of expandable aggregates that have been used to create concrete mixtures that are not only lighter but also more environmentally friendly. Reviewing the literature on the use of these materials in lightweight concrete, this paper focuses on their mechanical and physical characteristics, potential for architectural use, and environmental benefits. This study reveals the material benefits and sustainable objectives and performance of the material in architectural uses.
