There are several main differences between clay bricks and concrete blocks, in terms of composition and usage. As a building material, they should be carefully selected according to the type of project and the intended use of the building. We break down the benefits of each.
The differences between bricks and solid concrete blocks
Bricks and concrete blocks are made from different raw materials, meaning they have different structural compositions. Brick is made up of sand, lime and concrete materials, while concrete blocks are produced from aggregate consisting of crushed sand or stone.
Concrete blocks have a much higher water resistance than bricks, and their compressive strength is higher. Concrete has a shorter life than brick, though it still gives efficient results for up to 100 years. It is also incredible durable and can be painted more easily than brick, which secretes metallic salts that can cause paint to peel off.
One of the main advantages of solid concrete blocks is that they offer outstanding fire resistance and the very highest fire safety rating. They're often favoured for their thermal efficiency and sound insulation.
Which is better?
There is no simple answer to this, as it depends on the nature of your project and the intended use of the building. If sound insulation, fire resistance and thermal efficiency are priorities, then solid concrete blocks could be the right choice for your construction project. It's also worth noting that concrete blocks can be painted easier than brick can, giving you more flexibility in terms of design options and finishes.
About our solid concrete blocks
We supply high-strength 100mm 7.3N solid concrete blocks for use in cavity and solid walls, load-bearing and solid partitions, columns and block and beam flooring.
Our concrete blocks have a tolerance of D1, a mean compressive strength of 3.6 - 30N/mm2 (unit strength) and a shear bond strength of 0.15N/mm2 (tabulated value). Available in packs of 88, they are available for delivery or collection from our concrete plant in Avonmouth, where they are manufactured.
