Due to its C3A (aluminate) phase content, this cement offers moderate resistance against sulfate attack. Furthermore, owing to its moderate heat of hydration, it is suitable for use in relatively massive concrete pours. This cement has a minimum compressive strength of 42.5 MPa at 28 days.

In terms of raw materials, this type of cement has a composition similar to that of Type I Portland cement; however, because its C3A (aluminate) phase content is less than 8%, it offers moderate resistance against sulfate attack. Due to the relatively high quality of the raw materials, the use of appropriate equipment, precise proportioning of the raw mix, and rigorous product monitoring by the quality control department, the Type II Portland cement produced at this facility is of excellent quality and holds a distinguished position within the country. Some of the properties and characteristics of Type II Portland cement are as follows:
It is suitable for all applications where Type I cement is used. Due to its moderate resistance to sulfate attack, it can be employed in environments where the risk of such attack is moderate. It exhibits a relatively low initial heat of hydration, making it suitable for use in relatively massive concrete pours.
This type of cement is marketed under the trade name "Type II Portland Cement, Grade 42.5."
This type of cement is known as Ordinary Portland Cement (OPC). Based on its 28-day strength, Type I cement is categorized into three strength classes: 32.5, 42.5, and 52.5; it is used for general purposes in the production of mortar and concrete.
