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.
