Ordinary Portland cement Type I-525
Portland cement type I-525 has been defined as cement type one with a compressive strength of 525 kg/cm2 in ISIRI 389.
The major feature of this type is its similarity in chemical specifications to those of Portland cement type V. therefore this type can as well be called Portland cement type V with high anti-sulfate feature, with a compressive strength class of 525.
The type I-525 cement produced in MOMTAZAN meets better specifications than those mentioned in the standard documents, as a result of high quality raw material and meticulous quality control during production process.
In terms of compressive strength, this type is categorized as CEM I 52.5N according to the European standards.
Main Features:
-
Compressive Strength in 28 days is equal to 550 +_ 20 kg/cm2
-
Better application in precast units and lower maintenance costs
-
Ability to be used quickly particularly in cold climates
-
Possible reduction of consumed cement volume to achieve homogeneous concrete resistance
-
Chemical specifications of this type can allow it to be also used instead of Portland Cement type V
-
Ability to be absorbed in and fill concrete and cement cracks
-
Highly desirable increase in compressive strength and application in concrete ceilings and columns
