Full product specifications What you’re buying
One complete Portland-cement designation with 52.5 N and SR 3.
CEM I identifies Portland cement, 52.5 is the EN strength class, and N identifies normal early strength.
SR 3 is the documented sulfate-resistance category, giving buyers a complete designation for specification and pricing.
52.5
The EN cement strength class.
N
Normal early strength.
SR 3
The documented sulfate-resistance category.
