CEM I 52,5 R (wh)

White cement composed almost entirely of clinker, allowing for the production of white or coloured concretes with superior architectural performance. Good for both reinforced and prestressed concrete. Best suitable for works requiring very high strength at all standard ages.

Clinker ≥ 95%;
Additional minor constituents ≤ 5%;
Calcium sulfate as setting regulator.

Minimum growth curve

​​​

• White or coloured concrete with high architectural performance;
• Very high strength development;
• Very high strength at all standard ages.

• In apparent concrete, with high architectural performance, to ensure a uniform appearance;
• Pay attention to the water/cement ratio, aggregate quality, etc. during the mixed design;
• Ensure especial care in manufacturing and application (homogeneity of mixing, concreting phasing, framework quality, framework removal, etc.);
• Provide adequate protection and cure according to corresponding standards and aesthetic requirements;
• Placing concrete under hot weather.

• Wear proper protective clothing, gloves and eye/face protection equipment;
