CEBs, or Compressed Earth Blocks, are sustainable building materials made from a mixture of soil, sand, and a small amount of cement. They are compressed using a mechanical press to create strong, durable blocks that can be used in construction. CEBs are an eco-friendly alternative to traditional bricks, as they utilize local materials and require less energy to produce. These blocks offer excellent thermal mass, helping to regulate indoor temperatures and reduce energy costs. CEBs can be used in various architectural styles and are often employed in earth-sheltered homes and green building projects, promoting environmentally responsible construction practices.
