The construction technique is evolving day by day, from mud house to red clay building; the manufacturing procedure has changed a lot. Now there’s a growing demand for cheaper and faster technique bricks which can also be friendly to the environment. Here comes the need for substitution of traditional bricks.

Hollow blocks are an innovation in the building industry. These are made of concrete and use as an alternative to conventional red bricks. As the name suggests, the blocks have hollows in the middle; the void area is greater than 25%. These can be available in various sizes and shapes. Eco-friendly hollow blocks are great for their durability, speed of construction and cost-effectiveness.

Hollow Concrete Blocks Application:

• Exterior walls
• Partition and panel walls
• Curtain walls
• Boundary fences
• Piers, column and retaining walls
• Fire-safe walls around stairwell and elevators

Hollow blocks have some advantages that make these construction blocks popular nowadays.

Eco-Friendly
Unlike red bricks, concrete hollow blocks are machine made thus these unable to release harmful fumes and can save our nature. Their insulating properties reduce energy consumption and hence make these blocks energy-efficient building material.

Highly Durable
Due to high durability, concrete hollow blocks bear more load compared to AAC Blocks and Bricks.

Fast Construction
Speedy construction reduces the overall construction time. One can install the blocks easily due to their uniform size and shape. The construction work takes less time due to lightweight. Even semi-skilled or unskilled labourers can work with hollow bricks.

Earthquake Resistant
Concrete hollow blocks are lightweight thus these are highly earthquake resistant. The strong foundation reduces building load stability and vulnerability during natural disasters like earthquakes.

Dimensional Accuracy
Hollow blocks are best for load-bearing structures and partition walls for accuracy and consistent finish.

Cost-effective
Affordable price is another major advantage of concrete hollow blocks. One block replaces five traditional bricks and thus reduces the construction cost. The construction also requires less mortar and saves labour hours, which automatically reduces mortar and labour costs.

However, all these forms of brick layering have a few things that need to be addressed. The most important among that is the bricks must be of uniform size. The bricks must not absorb water more than 20% of its weight. There are also a few other guidelines that need to be followed.

Unique Hollow Nature Provide better Thermal and Sound Insulation

The air in the hollow does not allow outside cold and heat. So the interior remains comfortable in all weather, cool in summer and warm in winter. The blocks also make the building soundproof and damp proof due to its insulating properties. The blocks can be used also on rooftops for heat protection.
The blocks provide good bonding between mortar and plaster due to the rough surface. The high-quality, cost-effective and eco-friendly concrete hollow blocks now become the most preferred material in today’s construction. So, hollow blocks come first to mind whenever someone thinks of the best substitute for traditional bricks. Go for eco-friendly construction for a better tomorrow.
