Final answer:
The primary reason for providing core holes in bricks is to reduce their weight, which makes the construction process easier and less expensive. It also improves insulation and allows for uniform firing during production, leading to stronger bricks.
Step-by-step explanation:
The primary reason for providing core holes in bricks is to reduce the weight and improve the insulation properties of the brick. This also has the effect of using less material which can reduce costs. The holes enable better firing of the bricks during the manufacturing process, leading to a more uniform and stronger product. Moreover, the holes can facilitate the placement of reinforcement bars and the flow of mortar, which can increase the structural stability of the wall. It is important to note that the holes in bricks are intentionally designed and do not compromise the brick's strength when used within proper building practices.
It's essential to choose the correct bricks for the specific building project, and professionals in construction and engineering need to be aware of all the properties of the materials used. Core holed bricks are a common sight in modern construction due to their advantages. While the presence of holes can slightly change the way bricks are laid, it does not significantly alter the overall construction process. Ultimately, these specialized bricks serve to improve building efficiency and performance.
Therefore, referring to the abovementioned explanation, the correct option as the primary reason for providing core holes in bricks is to reduce the weight and improve the insulation properties while also reducing manufacturing and construction costs.
