In an RCC frame building, the walls carry no load: they only fill the frame. That gives you a real choice between traditional burnt clay brick and concrete or AAC blocks. Each has a place, and the right answer depends on your budget, your mason and how much heat you want to keep out.
Burnt clay brick
Brick is what almost every mason in Bangladesh knows how to lay, it is available everywhere, and it takes plaster and fixings well. Its downsides are weight, which adds to the load on columns and foundation, slower laying, and variable quality from kiln to kiln. Check that bricks ring clearly when struck and are fully burnt, not yellow.
Concrete and AAC blocks
Blocks are larger, so walls go up faster with less mortar. Lightweight AAC blocks weigh a fraction of brick, which can trim the structure's cost on taller buildings, and their trapped air keeps rooms noticeably cooler. They need the right adhesive and fixings, and a mason who has worked with them before.
How to decide
- Low-rise family home with a local crew: brick is simple and dependable
- Five floors or more: lighter blocks reduce the load on the frame
- West-facing or top-floor rooms: AAC's insulation makes a real difference
- Tight timeline: blocks lay faster, as long as the crew is trained
Whichever you choose, decide before the structural design is finished, so the engineer can size columns and beams for the actual wall weight.
