Buying guide
Which cement should I use?
Match the strength class to the job. Where a structural engineer has specified a class or mix, follow the specification.
| Job | Suggested class | Why |
|---|---|---|
| Block laying, mortar and plaster | 32.5N | Workable, smooth finish, right strength for the job |
| Block and paver production | 32.5R | Faster demoulding, quicker yard turnaround |
| Foundations, ground and suspended slabs | 42.5N | Structural strength most engineers specify |
| Columns, beams and precast work | 42.5N / 42.5R | High final strength; R for early striking |
| Water tanks and retaining structures | 42.5N | Denser, stronger concrete for water-tightness |
| Fast-track pours and cold-weather work | 42.5R | Early strength keeps the programme moving |
This guide is general advice, not a substitute for an engineer's specification.
