This type of cement possesses all the properties of Type 1 cement, with the distinction that it belongs to a higher strength class than the Type 1, Class 32.5 variant. In other words, according to the definition provided by the Iranian National Standard (389), the 28-day compressive strength of this cement must be at least 42.5 Megapascals (MPa).
Some of the properties of the cement produced at this facility include: 1) A reduction in the amount of cement required to achieve a specific mix design (cement content) in concrete. 2) Higher compressive strength compared to Type 1, Class 32.5 cement at the same age. 3) Faster formwork removal and earlier application of structural loads compared to Type 1, Class 32.5 cement. 4) The capability to produce concrete with higher strength grades. This product is marketed under the trade name "Type 1, Class 42.5 Portland Cement."
This type of cement is known as Ordinary Portland Cement (OPC). Based on its 28-day strength, Type I cement is classified into three strength classes—32.5, 42.5, and 52.5—with this specific variant representing the second class; it is used for general purposes in the production of mortar and concrete.
