A concrete block is primarily used as a building material in the construction of walls. A concrete block is one of several precast concrete products used in construction.
Blocks are beneficial to builders as they help speed construction but are extremely harmful to the environment as they score very high on both embodied carbon as well as operational carbon.
In Zambia, blocks come in 4-inch, 6-inch and 8-inch sizes. Types of blocks are Hollow concrete blocks, Aerated Autoclaved Concrete Block, Concrete Bricks, Solid concrete blocks, Lintel blocks and Concrete stretcher blocks.
Concrete blocks have greater compressive strength than normal clay bricks and have less water absorption property than clay bricks. Concrete bricks are generally made of cement, sand and stones. In Zambia, these blocks are generally used in building construction as well as wall fences due to their beautiful and modern aesthetic look.
