Recent advances in sustainable lightweight foamed concrete incorporating recycled waste and byproducts: A review
Graphical abstract Display Omitted
Highlights Comprehensive review of recent advances in incorporating wastes into foamed concrete. Utilization of various wastes as binder, aggregate, and modifier replacements. Effect of physicochemical properties of wastes on foamed concrete were analyzed. The challenge and development direction of waste-based foam concrete were discussed.
Abstract Globally, various solid wastes are produced and stockpiled in large quantities, causing serious environmental, social, and economic problems. Foamed concrete has attracted worldwide attention because of its excellent functional properties. Incorporating recycled waste and byproducts into foamed concrete is considered a win–win strategy for sustainable waste management and green transformation of foamed concrete. However, the reviews of alternative forms of different wastes/byproducts and their effects on foamed concrete are limited, which has hindered the promotion of this concept. Therefore, this paper compiles and reviews the reuse potential of various types of waste and byproducts as cementitious materials, aggregates, and modifier replacements. Together with the chemical and physical properties of the waste byproducts, the effects of different waste/by-product substitution pathways on the properties, pore structure, hydration products, and carbon emission reduction of foamed concrete were comprehensively evaluated. Our findings are important for guiding the rational introduction of wastes/byproducts and optimizing the combination of the inherent characteristics of waste byproducts and the requirements of foamed concrete. Furthermore, this review also discusses the challenges and development directions of waste-based foam concrete. This study provides an important basis and guidance for sustainable waste management, and low-carbon foamed concrete manufacturing.
