Portland Cement Type I

This type of cement is produced according to the requirements of ISIRI Standards No . 389,USA Standard / ASTM-C150 with chemical and physical properties similar to those of 32.5 cement but a higher heat of hydration , more rapid setting time as well as higher rate of initial and final resistance than 32.5 type.

Portland cement I-425 is used in all reinforced and non-reinforced concrete structures where , as compared to 32.5 type , early strength including columns , ceilings , bridge abutments and Structures requiring rapid molding are required and , also , it may be used in cold weather too Due to a higher heat of hydration it is recommended to control the application of this cement and solely use it in places with low disruptive effects of sulfate attack on concrete.
