The production of expanded clay involves heating clay pellets at extremely high temperatures in a rotary kiln. This process causes the clay to expand and develop a hard, ceramic shell with a porous interior. The result is a lightweight aggregate that offers impressive strength-to-weight ratios, excellent insulation properties, and remarkable durability. These characteristics make expanded clay an indispensable resource in various professional fields. In the construction industry, expanded clay is renowned for its ability to provide thermal insulation and soundproofing while maintaining structural integrity. Its lightweight nature reduces the load on structures, making it an ideal choice for high-rise buildings and renovation projects where weight reduction is crucial. As a filler material in concrete, expanded clay enhances the strength and reduces the overall weight, leading to significant cost savings in transport and handling. Moreover, its fire-resistance properties make it a safe option in building environments, contributing to enhanced safety standards.
