A cementitious material characterized by its low density, is achieved through the introduction of air or gas bubbles into a slurry of cement, water, and sometimes aggregate. This process creates a highly porous structure, resulting in a significantly lighter product compared to traditional concrete. These materials can be produced using preformed foam, gas-forming agents, or other methods that introduce and stabilize air voids within the mixture.
The advantages of this type of material are multifaceted. Its reduced weight translates to lower transportation costs, decreased structural loads, and simplified construction processes. Furthermore, it exhibits enhanced thermal insulation properties, leading to improved energy efficiency in buildings. Historically, its development stemmed from the need for lighter building materials, and its utilization has expanded across various applications due to its sustainable and cost-effective nature.
