Lightweight concrete is a type of concrete that has a lower density than traditional concrete. It is made by incorporating lightweight aggregates, such as expanded clay, shale, or pumice, which reduce the overall weight while maintaining strength. This makes it ideal for applications where reducing the load on structures is important. Due to its lighter weight, lightweight concrete is often used in construction for floors, roofs, and precast elements. It also provides better insulation properties, making it energy-efficient. Additionally, it can help reduce transportation costs and improve workability on construction sites.
