Various Types Of Bricks For Building
Various Types Of Bricks For Building : The brick business uses a variety of brick varieties. Learn more about them by reading the article.
Any building’s construction entails a wide range of activities. Cement, sand, soil, and, most significantly, bricks are among these components. Every construction would be lacking without bricks. Therefore, it is crucial to be aware of the many kinds of bricks used on a daily basis to build homes, the shopping centres we frequent, hospitals, schools, etc.
The origins of bricks
No other construction material has yet to equal the bricks’ timeless beauty and elegance. The first bricks ever found date around 7000 BC and were initially constructed of mud. Earlier, clay-bearing mud or soil was used to produce bricks, which were then dried until they were sturdy enough to support the entire building.
Bricks are one of the most widely accessible building materials, therefore their primary usage is in the construction of wall units. At least 75% of the bricks are comprised of solid materials. As new methods of manufacturing them have been found, they are now now divided into many categories.
We’ll talk about the many kinds of bricks here. The most popular types include sand lime bricks, fly ash bricks, concrete bricks, burned clay bricks, sun-dried clay bricks, and engineering bricks.

Principal types of brick
Fired clay bricks
- These bricks are employed in the construction of foundations, walls, columns, and more.
- They are referred to as “common bricks” since they are often utilised in building.
- Bricks must be plastered or rendered with mortar by construction workers in order to increase the bricks’ strength, water resistance, and insulating properties.
Again, there are four categories for these bricks: first, second, third, and fourth classes. The majority of bricks used in modern building are of this flexible kind.
Various Types Of Bricks For Building -Sun-dried clay bricks
These bricks, which are among the earliest, were utilised in Southern Turkish regions and towns like Jericho in modern-day Palestine.
- The strength of these bricks is insufficient for usage in load-bearing structures.
- They are also not the strong kind since they are the weakest members of the group. These are mostly employed for transient masonry.
- These bricks are made of a combination of straw, loamy soil, and water. Sand, clay, or manure may be used by brick manufacturers to strengthen their product and keep it from breaking.
- The mixture is poured into a mould and let to dry in the sunlight. These bricks are taken out of the mould after drying and put to use.
- The fact that these bricks are reasonably priced is a plus.
- Solid concrete is used to create this style of brick. The mixture is then put into specially made moulds so that they can have various shapes and sizes.
- It may also be created right there on the job site by combining cement, sand, and other materials. aggregates with a 1:2:4 ratio. By making a minor adjustment to the mixture, one may also improve the strength. In that situation, the ratio of cement, sand, and aggregates in the mixture would be 1:3:6.
- These concrete bricks are used for internal brickwork, exterior walls, and facades.
- They possess the necessary properties to be employed as load-bearing materials, including high density and compressive strength.
- These bricks don’t absorb a lot of moisture due to their low absorption levels, which prevents them from crumbling, cracking, or leaking.
- In addition, most engineers believe it to be the greatest brick.
- Engineering bricks also have a low amount of porosity, which protects them against toxins that may otherwise get inside of them.
- Due of their remarkable characteristics, including strength, density, and more, they are frequently used for retaining walls, sewers, manholes, and basement foundations.
Bricks made with fly ash
- Class C or F fly ash, cement, quicklime, aluminium powder, water, and gypsum are used to make these bricks.
- By being recycled, fly ash bricks assist in lowering the quantity of harmful metals discharged into the environment.
- It is a byproduct of coal-fired power plants, which also produce mercury, chromium, and other hazardous metals.
- They have a highly regular shape since they are produced in a machine mould.
- These bricks are available in tiny sizes because as brick size grows, its durability reduces, causing slab fractures.
- They can be used in place of burned clay bricks due to their high compressive strength and low absorption rate.
Various Types Of Bricks For Building – Sand-and-lime bricks
- Sand lime bricks are a common choice for creating load-bearing walls in homes and tall buildings because to their great compressive strength.
- Sand, lime, and maybe a colour pigment are used to make them. Bricks with a smooth, uniform surface that are perfect for building projects can also be produced by accelerating the chemical reaction with heat and pressure during the manufacturing process.
- These bricks’ greatest advantages are their fire resistance and acoustic insulation, which shield the structure from fire and noise.
- They are primarily employed for building hospitals, schools, etc.
- This brick is formed of fireclay, a silica and alumina-containing clay. They are able to resist temperatures of more than 3000 degrees because of this.
- Low temperatures and abrupt shifts between hot and cold weather are no problem for it.
- Walls and buildings made of these bricks are extremely heat- and fire-resistant, including chimneys, fireplaces, brick barbecues, and fire pits.
- They would never succumb to heat stress and fracture, shatter, or break. Because of its important characteristics and qualities, this kind of brick is among the best.
Other types of bricks based on quality and raw materials
Various Types Of Bricks For Building 1) Considering the standard
These bricks feature smooth surfaces, sharp edges, and are manufactured of high-quality clay. They are also regular in size and shape. They are so badly burned that they acquire a cherry red or copper colour. When tapped, these bricks emit a ringing sound. They are high-quality bricks utilised for a variety of excellent natural construction projects.
These bricks have a medium quality since they were formed using ground moulding. They generate ringing noises like first-class bricks while having some form and structural flaws. Even these bricks can be used to build long-lasting, even load-bearing constructions.
Third class bricks
Third-class bricks are of low quality, with unfair edges and uneven forms. They are burned in clamps using ground moulding. Occasionally be overburnt or underburnt because of this. They are mostly used to build temporary constructions because of the aforementioned reasons.
Brittle and not at all durable for use in construction, these bricks. They are crushed so that they can be used in their broken form for building foundations, roads, and other things. They are employed in the production of brickbat concrete.
Various Types Of Bricks For Building 2) Depending on the inputs
Silica bricks are an illustration of this kind of brick. With the melts of the fundamental component, they will react. But they can withstand melts that are acidic.
They are also referred to as alkaline bricks and should not be used in furnaces to heat acidic melts. Such bricks include those made of magnesium and bauxite.
They do not react with melts that are acidic or basic. Examples of these kind of bricks are chrome-magnesite and chromite bricks.
Bricks from Ganister
They have a dark colour and include 10% clay. Around 1800°C is the maximum temperature they can endure. Ganister bricks, which are used for lining furnaces, are quite similar to silica bricks.
Various Types Of Bricks For Building: Painted bricks
The ideal materials for making glazed bricks are fireclay or shale. Two firings are used to produce and fuse the ceramic covering on these bricks. They are beautiful and strong, and are utilised in both interior and exterior construction.
