Regardless of the cost, in terms of building quality, which is better, red brick or perforated brick? Can a six-story building with pure brick and concrete be built with red brick? Why?

1. In terms of quality (structural stability and seismic performance of buildings), solid red bricks are much more reliable than porous bricks (that is, hollow bricks as you said).

In areas with good foundation, brick-concrete buildings can be built to more than 8 floors. However, due to the strong national regulations, elevators must be installed in buildings above 8 floors (including 8 floors). Therefore, brick-concrete buildings are generally built below 8 floors, which means that solid red bricks can be built to more than 24 meters. Of course, the columns and beams in the house are still reinforced concrete, but the main load is brick walls.

2. Porous brick can bear load, but its bearing capacity is weaker than that of solid, so at present, most of the external walls of buildings with frame or frame-shear structure use porous brick as separation and waterproof function.

3. In towns and villages, most houses are solid red bricks. Because there are not many floors, solid bricks are used on one floor and perforated bricks are used on it, which can reduce the cost and the weight of the wall on the foundation.

4. If there are not many floors, you can use empty ones, but the bottom few leather bricks or at least 2 meters below the ground and above the ground beam must use solid bricks to prevent moisture. The moisture-proof and waterproof performance of hollow brick is much worse than that of solid brick.
