Description

Cement III/A 42.5 R is a blast furnace cement with a 42.5 resistance class with high early strength conforming to UNI EN 197-1.

Composition

Cement III/A 42.5 R is composed of a percentage of clinker between 35 and 64%, a percentage of blast furnace slag between 36 and 65% and a maximum of 5% secondary components.
These percentages do not take into account the addition of calcium sulfate and of additives.

Conformity

The cement conforms to UNI EN 197-1, UNI 11834 for IAS certification and 305/2011/UE (CPR) guidelines.
