Why are cinder blocks hollow?

These hollow blocks allow the adoption of thinner walls which ultimately results in increased floor space, since the air space in the block is 25% of the block’s total area, this saves the material. As the blocks are precast, its surface is smoother therefore requires less plastering material.

As the hollow concrete blocks are light in weight, they reduce the weight of the structure and hence light structural member or less percentage of steel is required for a given R. C. C building. Presence of rough texture on concrete blocks provides good bonding between cement mortar and concrete blocks.

Some articles claimed these holes or cavities reduce the total cross-sectional area of the block and hence the weight of block structure as a whole. Hollow concrete blocks are more commonly used in masonry construction.

It is possible to construct a thin wall by using hollow blocks. Therefore, it helps to save space and increase the floor area or carpet area, i., and e. Carpet area efficiency is better.
