Lightweight concrete blocks are building materials made from a mixture of cement, water, and lightweight aggregates such as expanded clay, expanded polystyrene, or perlite. These blocks are designed to be lighter than traditional concrete blocks, making them easier to handle and transport. They provide good insulation and can help reduce energy costs in buildings. Due to their reduced weight, lightweight concrete blocks are often used in construction projects where minimizing structural load is important. They are commonly employed in walls, partitions, and other applications, offering a balance of strength and thermal efficiency while being environmentally friendly.
