Portland cement type 2

This type of cement is suitable for general applications, for concrete-making, foundation and etc. It is appropriate for environments where there is a risk of sulfate attack or for places where the sulfate concentration in the underground water or soil is higher than the normal level.

Generally, this type of cement is better than the other types of Portland cement in environments where the concrete is exposed to chemical attacks such as sulfate and chlorine jointly. As a result, this type of cement is proved to have the best application in various constructional activities.
