Let’s take a look at the different types of bricks available that you can choose from.
Types of Bricks
1. Burnt Clay Bricks
When people say bricks, this is what they usually mean. One of the oldest and most used types of bricks today is the burnt clay bricks. Its characteristic dark orange color has been around for centuries. It provides a robust structure that is reasonably fire and weather resistant. But for improved aesthetics, you might need to plaster on it for a smooth finish.
2. Concrete Bricks
Concrete bricks are usually made from a mixture of high strength cement as bonding agent, water, and sand. These types of bricks are known for their high strength and durability and often used in construction of walls or pathways. They are highly weather resistant and durable. It should be noted that they are heavier than clay bricks and require proper sealing to prevent moisture seepage.
3. Sand-Lime Bricks
Sand-lime bricks or calcium silicate bricks are an alternative to concrete bricks. It is similar to concrete bricks but it uses lime instead of cement as a bonding agent. These types of bricks need to be cured in an autoclave and are strong enough to be used in load-bearing walls or high-rise buildings. It has good thermal insulation and has a uniform shape which makes it a good choice for commercial construction.
4. Fly Ash Bricks
Fly ash bricks are made from the residue of burning coal and mixed with water and other additives for bonding. It requires a specialized curing process under high-pressure to ensure it can be used. It has several advantages for construction being light, strong, and environmentally friendly. Since the edges are prone to chipping off, it needs careful handling which makes it a slightly more expensive option.
5.Engineering Bricks
Engineering bricks are the choice for more demanding projects. These bricks are designed to be the highest strength with as low water porosity as possible. While these are also made with clay, the process is different, and the result is focused on a more durable product without any need for aesthetics. They are much more expensive than regular burnt-clay bricks.
Brick Properties You Should Know
1. Density and Weight
Ideally, the best option for bricks is to have a balance between density and weight when you’re looking at domestic construction. For commercial purposes, since the buildings are going to be larger and have multiple floors, you need denser material to form a proper load bearing base. Your contractor will be able to help you with the choice of bricks for your needs.
2.Compressive Strength
Compressive strength is how much axial load (vertical load) a brick can withstand before being crushed. Needless to say, this is important for all types of construction. The compressive strength depends on the type of material and curing process of a brick. While engineering bricks have one of the highest compressive strength numbers, you might not need them for a two-story home.
3. Durability and Weather Resistance
Durability is a vital factor for all types of bricks. The ability of the brick to resist external factors like weathering and wear is referred to as its durability. High durability is generally better, and this can be further enhanced by the use of protective coatings. Also, the choice of bricks is determined by the type of weather in the area.
4. Water Absorption
Water absorption or porosity is a measure of the water intake experienced in a brick and is usually expressed as a percentage of its weight. So, for a brick that weighs 100 gms and has 6% water absorption, it will take in 6 gms of water. Regardless of the type of brick you choose, ensure that it has low water absorption, especially if you live in a rainy or wet climate.
5. Cost
The one factor that mostly dictates the choice of what brick you’re going to use comes down to the cost. It should be noted that burnt-clay bricks are more expensive than concrete bricks. The reason is due to the choice of raw materials and the curing process. While some types of bricks may be more expensive, they may be more durable saving you maintenance costs down the line.
There are many factors to choose the right brick type for your construction needs. If you’re investing in a project, you have to look at the cost to performance ratio rather than the cost alone.
