Breeze blocks are a type of construction material that are made up of concrete and coal cinders. They are also known as cinder blocks and concrete blocks. They are used in the construction of foundations, walls, and other types of structures due to the widespread recognition of their durability, affordability, and strength, respectively.

When making breeze blocks, a mixture of cement, water, fine aggregate (such as sand or crushed stone), and coarse aggregate is required (such as coal cinders). After that, the substance is poured into a mould, and then it is allowed to cure, also known as become solid. After the blocks have been allowed to fully cure, they can then be made ready for use in construction.

Together with reinforcing steel bars, breeze blocks are a common component used in the construction of load-bearing walls. This helps to improve the structural integrity of the walls (rebar). In place of brick or stone, which can be prohibitively expensive, they are typically utilised in the construction of dividing walls and walls that do not bear the load of the building.

Breeze blocks can also be utilised in settings that are more concerned with aesthetics; nonetheless, in terms of design, they are most usually used to produce a utilitarian or industrial look. They are available in a wide range of dimensions, contours, and hues, and can be arranged on walls and other surfaces to produce a variety of patterns and designs.
