In my view brick masonary gives better architectural view than conc. block.
The strength of brick wall is more than conc. block.
It is easy to make recess easily for pipe, holdfast and other fixing in the brick wall. less crack in plaster than conc. block wall.
Conc wall is better in pation wall.Being big size work done fast speed, low water consumption. Seepage and cracks in plaster occur.
