Sulfur-resistant cement (32.5)
A hydraulic cement produced by milling Portland cement clinker containing max 5% tricalcium aluminates together with a given quantity of gypsum.
Produced in compliance with TS 10157 standards.
Typically SDC 32,5 can be used in places where ordinary Portland cement is used.
Since it has a C3A ratio less than 5% it is technically much more convenient in the areas that are subjected to higher sulfate rates such as tunnels, dam constructions, port constructions, irrigation channels, building chemicals etc.
Fields of use include:
- Shore and Port Structures
- Off shore constructions
- Disposed Water Facilities
- Foundation, Bored Piles
- Water Arcs
- Dams
- Underground water pipes, of concrete
- Sulfate contaminated industrial grounds and structures
- Refineries
- Tunnel Shoring
