Burnt clay bricks Vs Concrete blocks, which is better?

A burnt clay brick is a building material made of clay bearing soil, sand and lime or concrete with its standard measurement being. The rectangular units are joined together using mortar, adhesives or by interlocking them and are in various sizes depending on what they are used for. Concrete blocks are similar to bricks, only larger and heavier weighing; One block is equivalent to four bricks. Blocks are made using cement or concrete and are used for a wide variety of purposes such as the construction of load bearing walls, retaining walls, partitions and foundations. Both of these building materials are used all over the world but one might be preferred in some cases over the other and here is why;

  • Strength

Blocks are stronger than bricks. This is because they are made out of concrete or cement, components that are way heavier than clay, sand or lime. Due to such a quality, a house constructed using blocks will last much longer than one constructed with bricks. However, bricks have a high compressive ability which is a very good quality

  • Duration of construction

Constructing a wall using blocks will take a much shorter time than bricks. This is because, as mentioned earlier, one block is equivalent to four bricks. It is also much easier to estimate the number of blocks to be produced from a given amount of concrete than it is for bricks because of their porosity. However, their porosity nature is useful in regulating temperature and humidity in structures.

  • Cost

Bricks have lower maintenance costs compared to blocks and their raw materials such as sand, clay and lime are readily available hence affordable. Blocks on the other hand are quite costly right from the material which is cement and concrete to the finished material. Cement is quite is readily available but not really affordable by anybody. 

  • Environmental impact

For burnt bricks, a lot of trees have to be felled and converted into firewood to burn the bricks and make them come out hard. This entire process has disastrous effects in deforestation and environmental pollution. Blocks on the other hard are dried using automated heaters that have no impact on the environment.

  • Aesthetics

Bricks can be used in different colors, sizes and orientations to get different surface designs that beautifies a building. Blocks on the other hand are not good looking, concrete is not easily covered and is difficult to visually enhance. 

  • Weight

Bricks, due to their raw materials ae quite light. This makes them easy to move around the construction site using conventional methods too which reduces site costs. Blocks on the other hand are very heavy, one would need machines such as pulleys to move a up block especially on high rise structures. This will automatically increase the budget

  • Recyclability

Bricks are made from materials that can be easily recycled and used for landfills. The same cannot be said about blocks. They are not as recyclable as bricks as they are made concrete. All the renovation work that calls for breaking down of old structures to build new would only leave behind heaps of waste products that cannot be recycled.

  • Quality

The quality of blocks is extremely good as compare to that of the bricks. When a concrete block falls, it stays intact and can be used again. However, when a brick falls it becomes completely dismantled and cannot be used again.
