26–28mm aggregates are large-sized crushed stones known for their high load-bearing capacity and structural strength. These aggregates are widely used in heavy-duty concrete mixes where enhanced durability and support are essential. Their size makes them particularly effective in reinforced concrete applications, such as for industrial floors, foundations, and precast concrete elements that must withstand substantial weight and pressure.

In road construction, 26–28mm aggregates are often used as base layers or sub-base layers, forming a strong and stable foundation for pavements and highways. Their angular shape allows for better interlocking, which improves the compaction and load distribution of the road surface, minimizing the risk of deformation or settlement over time.
