Enhancing Thermal and Acoustic Insulation in Aerated Concrete: Role of Aluminium Powder as a Foaming Agent
Keywords:
Aluminium, Foaming, Powder, ChemicalAbstract
Aerated concrete, also known as cellular or lightweight concrete, is a unique construction material that has gained widespread use due to its thermal insulation, reduced weight, and fire resistance. One of the most common methods of creating aerated concrete is through the use of aluminum powder as a foaming agent, which releases hydrogen gas and creates the characteristic air-filled pores in the material. This review paper provides an in-depth exploration of the properties, production methods, and applications of aerated concrete utilizing aluminum powder. Various studies are examined to evaluate the mechanical properties, thermal efficiency, environmental impact, and structural integrity of aluminum powder-aerated concrete. Fifteen studies are cited to comprehensively address the current state of knowledge and potential advancements in this field.
