Portland Cement (PC 42.5 - PC 32.5) (CEM I 32.5 R - CEM I 42.5 R)

A hydraulic cement produced by milling Portland cement clinker (TS 3441) together with gypsum. It is classified as PC 32.5, PC 42.5, and PC 52.5. "PC" is the symbol for Portland cement while the numbers 32.5, 42.5, 52.5 indicate the minimum desired strength value achieved within 28 days.

Produced in compliance with TS 19 EN 197-1 standards.

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.
