JMC CEM IV
The cement is produced by grinding a mixture of additives (pozzolana) prescribed by standards (max. 20) with Portland cement clinker by addition of a certain amount of retarder (gypsum) and sets and gains strength after a certain time being mixed with water.
Generally the product can be used in all places where portland cement is applicable. Hydration temperature is relatively lower than portland cement. It is appropriate to use in concrete works performed in aggresive areas where the content of sulphate or chloride ion is high.
