Types Of Bricks


As a building material, bricks are versatile and can be used for various functions, including providing structural support and aesthetic appeal. It is common for them to be laid out on a flat surface and glued together. About eight inches in length and four inches in thickness, most bricks are. These are the most used bricks in construction, and you should be familiar with them.

Common Clay Bricks

The oldest and most widely used building material is Common Burnt Clay Bricks. Among the many things they help build are masonry walls, foundations, columns, and a host of other structural elements. Pressing and kiln firing are the steps involved in creating these ceramic artifacts. Because they don’t have particularly eye-catching aesthetics, these bricks are more commonly utilised in everyday construction. Using burnt clay bricks in a wall necessitates plaster or rendering. You can find several professional bricklaying agencies in Sydney that produce this kind of brick.

Limestone Sand Bricks

Sand lime bricks are created by autoclaving a sand, lime, and water mixture (with no additions) under high pressure to harden it into a white brick. There are several advantages to using this type of brick over the clay, including the fact that it is grey instead of reddish, the shape is smoother and doesn’t require plaster, and it is strong enough to be used as a load-bearing part. Sand lime bricks are also favoured by architects because of their excellent acoustical, thermal, and fire-resistant properties.

Bricks for construction

Class A and Class B engineering bricks are available with professional bricklaying, but Class A is more commonly utilised. This brick is sold for its physical properties, not its appearance. An engineering brick is a compact, full brick with great compressive strength and little water absorption since it is made at exceptionally high temperatures. Class A engineering blocks must have a compressive strength of more than 150N/mm2 and an absorption rate of less than 4.5% as a damp-proof course brick. More than 75N/mm2 compressive strength must be achieved and less than 7 percent water absorption in Class B engineering bricks for the product to be considered. The strength, damp-proofing, and chemical resistance of engineering bricks make them ideal construction materials. Specific tasks call for the usage of these bricks, which can be more expensive than standard bricks.

Bricks Made of Concrete

CMU (concrete masonry unit) is another name for concrete bricks, a common building material used primarily to construct interior walls. These bricks can be made in various colours by adding pigment by the bricklayers, making them ideal for use on facades and fences. Concrete bricks are typically made from a mixture of powdered cement, water, sand, and gravel. This results in a light grey block with fine surface roughness and high compressive strength. 17.2-19.5 kg is the average weight of a concrete block. Concrete used for blocks often contains a higher proportion of sand and a smaller proportion of gravel and water than other types of concrete.

Bricks made with fly ash clay

At around 1000 degrees Celsius, bricklayers add fly ash to clay to create fly ash clay bricks. When compared to traditional clay bricks, they are a serious contender. The indirect savings in labour and mortar usage from using fly ash bricks are considerable. When these bricks come into touch with moisture and water, specific tests have shown to expand. With the rise in the number of thermal power plants, this type of brick is also wrong for the environment. A substantial amount of land is needed to dispose of fly ash, which pollutes the air and water and takes up significant space. When making bricks for building reasons, government organizations have proposed using fly ash and clay.
