CEM I 52,5 N

This type of cement consists primarily of approximately 90% clinker, 5% limestone, and 4-5% gypsum. It is required to achieve a compressive strength of x ≥ 20 MPa within two days and x ≥ 52.5 MPa within 28 days. Other important specifications for this cement include a maximum Loss on Ignition of 5%, Insoluble Residue of 5% or less, an SO3 level not exceeding 4%, and chloride content ≤ 0.10%. These properties ensure its suitability for various construction applications where both early and 28-day strengths are crucial, alongside controlled levels of chemical additives.
