CEM II/A-LL 52,5 R (wh)

White Portland-limestone cement consisting of clinker and filler. This cement produces white or coloured concrete with a high aesthetic value. Suitable for all strength classes.

80% ≤ Clinker ≤ 94%;
6% ≤ Limestone ≤ 20%;
Additional minor constituents ≤ 5%;
Calcium sulfate as setting regulator.

Minimum growth curve

​​​

• White or coloured concrete with high aesthetic effect;
• High strength development;
• 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 correspondent standards and aesthetic requirements;
• Placing concrete under hot weather.

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