Blocks vs Bricks

Can you tell the difference between Concrete Blocks and Clay Bricks? They have a lot of differences in their composition and usage.

The first striking difference between a brick and a block is in the shape, size, and composition. Blocks are mainly made of concrete and are larger in comparison to bricks. They come in both solid and hollow format and are used mainly in load bearing walls where strength is very important.

Brick are considered as one of the most environmentally friendly building materials in the market. Bricks are actually a great insulators; heat energy from the sun during the day will be stored and only released for several hours after sunset. This feature makes them suitable for areas with high temperatures. Moreover, they tend to expand after manufacture in the first few years of their life – about 3mm to 5mm over 10 meters of wall length, making it necessary for provision of expansion joints. In general, size, usage, purpose and composition of bricks and blocks make the difference.

Blocks, on the other hand are commonly made from concrete. Block are larger size than brick and are often used as partitions in both interior and exterior applications as well as forming the structure of a building. Most concrete blocks have one or more hollow cavities, and their sides may be cast smooth or with design. To form the wall, concrete blocks are stacked one at a time and held together with fresh concrete mortar.
