Can bricks 180 and 240 be mixed? Can bricks 180 and 240 be mixed?

Yes, it depends. Where did you build it? Because it needs both stability and beauty. Ordinary red brick is 24cm long and 12cm wide. Generally, the wall thickness is 24 (excluding the wall skin, that is, one brick thick), 37 (one brick and a half thick with a seam in the middle) and 49 (two bricks thick), so there is a seam in the middle of a wall with more than one brick. Therefore, when laying, the interval between layers is generally 1-3. It depends. Where did you build it? Because it needs both stability and beauty. Ordinary red brick is 24cm long and 12cm wide.
