DURAPRO is an eco-friendly product with low CO₂ emission with good durability behavior on carbonation, chloride penetration, and sulfate environment. Durapro is developed by the optimum combination of Portland cement and superfine powder of blast furnace-slag. DURAPRO is produced in accordance with European standards EN 197-1:2000 CEM III/A and fulfills the specification of ASTM C595/C595M-14 Type IS (50). DURAPRO is designed for construction projects where high resistance to aggressive environments and low heat hydration is required. Low heat of hydration is beneficial for the magnitude of the thermal stresses due to restraint conditions during the hardening of massive concrete volume.
