Hollow Blocks

As the name suggests, hollow concrete blocks have void space that is more than 25% of the total area. Therefore, lightweight aggregates are used to create them. These are simple to install and lightweight blocks. Hence, most of the hollow blocks are used in internal partition walls, architectural design, and for rooftop heat protection.

A critical part to examine:

 Water absorption is critical before considering getting a concrete block for construction. Poor water absorption will affect the quality of the bond strength. A 50–60% water absorption will have poor longevity of the structure. In simple words, the lower the water absorption, like 2%-4%, the better the durability feature of the concrete block.

Advantages of using the hollow concrete block:

 Concrete hollow blocks are sturdy and can bear a lot of loading since they are compressed by high pressure and vibration. Moreover, they are fire resistant and have a high degree of being saline. Adding to this, hollow concrete blocks are inexpensive and durable too.
