The concrete block which has a core-zero area of more than 25% of the total surface area is known as a hollow block.
Hollow blocks are lighter than conventional concrete blocks. These types of blocks are used for partition walls.
Hollow blocks took less material which is why they are very light in weight. One more advantage of the hollow block is they are very cost-efficient. Sometimes thermal insulation is provided in the hollow space of the concrete block.
Due to its lightweight, they reduced the dead load on the structure. Hollow blocks provide a very economical building design.

Features of Hollow Blocks:
- They have more than 25% air space of the total block area.
- They are very lightweight compare to traditional concrete blocks.
- Hollow blocks save material cost due to the presence of holes.
- They are very compatible with electrical and plumbing fixtures due to the presence of holes.
Advantages of Hollow Blocks:
- It saves material cost.
- They are very lightweight and easy to transport.
- Placing is easy.
- They provide thermal insulation.
- Hollow blocks are good for sound insulation due to cavity space.
- They are fire-resistant.
Disadvantages of Hollow Blocks:
- Bearing capacity is very poor.
- Compressive strength is less compared to traditional concrete blocks.
Uses of Hollow Blocks:
- Hollow blocks are used for the construction of partition walls.
- They can be used for temporary structures.
Size of Hollow Blocks:
The most common sizes of hollow blocks are as follows:
- 0.40 m x 0.20 m x 0.30 m.
- 0.40 m x 0.20 m x 0.20 m.
- 0.40 m x 0.20 m x 0.10 m.

Summing-Up
Usually, Hollow Block is a Type of Concrete Block used to construct internal and external walls. Hollow concrete block saves time in building walls because of their large size compared to bricks. Because of the load-carrying capacıty, the Hollow Block is assuming a significant part in the construction industry.
Hollow blocks are made utilizing molds and an appropriate added substance relying upon your location and your project. It is accepted that concrete blocks are one of the most well-known development materials which are utilized in the development business all over. Cement is used in order to produce stronger and longer-life hollow blocks.
