Portland cement type 1-425





(According to Iran National Standard, No 389) it is categorized as type II portland cement with strength grade of 425 kg/cm2. Its characteristics include similarity of chemical compound with type II portland cement. So this cement can be called type II cement with strength grade of 425.

So this cement is of better quality than values specified in the standard, due to the appropriate quality of raw materials and precise control in the production process, while the quality is uniform, the cement has superior characteristics over the values specified in the standard. Increasing the speed of operation in construction due to the high initial strength of concrete is another advantage. Consumption of this type of cement is not allowed in sulfated and chlorinated environments.
