Sulfur-resistant cement (SDC 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
