150x200x600	350	2	For light-to-medium column applications
200x200x600	350	2	Moderate structural load support
250x200x600	350	2	Enhanced load-bearing capacity
300x200x600	350	2	Suitable for heavy column designs

Mark column placement and align with project plans.
Lay a mortar base to secure the first course.
Place O-Blocks vertically with aligned courses. Maintain even staggered mortar joints.
Insert vertical rebar through the hollow core before pouring.
Fill the core with structural concrete to the required height.
Allow the grout to cure in line with concrete-setting best practices.

Structural Columns

Used as a substitute for traditional concrete or steel columns in mid- to low-rise buildings. Simplifies formwork and speeds up structural work.

Framing & Support

Ideal for strengthening corners, openings, and transitional structural zones where vertical loads must be managed effectively.

Seismic Zones

AAC O-Blocks contribute to energy absorption and stress distribution, supporting design standards for seismic resilience.
