CEM I 52,5 R is a pure Portland cement with a small amount of gypsum added (to regulate the setting time) and up to 5% other mineral admixtures. It is characterized by high strength (in the early and late stage), but also by relatively high heat during hydration. The higher temperature released during hydration is favorable in cold-weather concreting conditions and reduces the risk of the fresh concrete freezing.
Properties and benefits:
- Combined with various additives, it can be used in the production of concretes with a wide range of applications.
- Consistency and constant reliability in construction.
- It has color fastness and is ideal for architectural buildings that are always visually exposed.
This type of Portland cement is used mainly in applications of precast and ready-mix concrete, as well as in dry mixes with hydraulic properties. It is ideal for use in precast elements, prestressed concrete, etc. All standard concrete additives (retarders, plasticizers, etc.) can be used with our CEM I 52,5 R.
Declaration of Performance and CE marking
Our cements comply with the MKC EN 197-1 harmonized European standard and are subject to assessment and performance verification procedures by a third party (an EU authorized body under System 1+ for assessment and verification of consistency of performance).

Health and safety
Contact with wet cement, wet concrete, may cause irritation, dermatitis or severe chemical burns. Cement dust coming into contact with bodily fluids (such as sweat or tears) may cause irritation, dermatitis or burns. This carries a serious risk of eye damage. Wear appropriate, impermeable clothing, gloves and eye and face protection. In case of contact with the eyes, rinse them immediately with plenty of clean water and seek medical help. After skin contact, rinse immediately with plenty of clean water. Keep out of reach of children. Contains chromium (VI). Chromium with oxidation state VI, the concentration of which must not exceed 2ppm in bagged cement, is reduced for additional protection. May cause allergic reactions, the risk of which is higher if the cement is used past the expiration date stated on the package and the shipping documents.
