PORTLAND CEMENT CEM I 42.5 R
A hydraulic cement produced by milling Portland cement clinker (TS 3441) together with gypsum. It is classified as PC 42.5, and PC 52.5. "PC" is the symbol for Portland cement while the numbers 42.5, 52.5 indicate the minimum desired strength value achieved within 28 days.
Produced in compliance with TS 19 (Turkish), EN 197-1 (British) and (American) standards. The quality is also in compliance with Russian standards and the factory has the certificate enabling us to export to Russia.
It is generally used in works requiring high strength values, concrete works performed at low temperatures, precast buildings, tunnel-form applications, building chemical maunfacturing and foundations.
