Which new wall material is the best substitute for red brick? Shale brick? Concrete brick? Or something else? What are their advantages and disadvantages?

I don't think this problem can be generalized. As we all know, the building forms of our country have changed greatly at this stage. From the earliest brick structure to the later brick-concrete structure to the present frame structure. There are some differences (purely personal understanding, please correct me if it is incorrect): the brick structure is mainly blue brick and red brick; Brick-concrete structure is mainly composed of brick and concrete, but brick is mainly used for bearing and concrete structure is mainly used to stabilize the structure; The frame structure is mainly reinforced concrete structure, supplemented by other filling materials (mainly used for partition); Because of the convenience of space utilization brought by the variability of frame structure, frame structure is popular not only in cities, but also in rural areas. Frame structure has the following advantages in high-rise buildings: the low density of filling materials can reduce the cost of foundation treatment, and at the same time, it can increase the height of building floors-the pressure limit that the ground can bear, especially in the urban center where land is scarce. Due to the popularity of frame structure, lightweight and low-cost alternative materials will be popular; So it is either aerated concrete block or cheaper filling material (regardless of weight).
