When choosing fly ash bricks for your building, it is important to consider both the structural design of your property and the load-bearing requirements of the walls. Will the bricks be used primarily for inner partition walls, or will they be used for heavy-duty outer structural foundations? Do you want a standard residential finish or a more robust industrial look?
There are many different types of fly ash bricks to choose from, so it is important to narrow down your options before making a final decision. Once you have decided on the class of bricks you prefer, you can then choose the exact size and compressive strength that best suits your project.
Fly ash bricks can be manufactured to various specifications, including standard solid formats, interlocking blocks, and hollow designs. The most popular grading strengths for structural brickwork are 7.5 N/mm², 10 N/mm², and heavy-duty 15 N/mm².
If you are unsure of what style of fly ash bricks would best suit your construction, it is a good idea to consult with a structural engineer or professional brick manufacturer. They will be able to help you choose the right strength for your specific needs.
