Ready-mixG15
G15
A lower strength class, often requested where the concrete is not acting as the structural element.
Often requested for
- Blinding under footings and ground slabs
- Lean mix and mass fill
- Bedding and non-structural work
The number in a grade such as G30 is commonly treated as the strength class in N/mm². That is industry naming, not a T3 test result. Your engineer specifies the grade. T3 confirms what can be supplied when quoting. This page is not an engineering design.
