White Cement CEM I 52.5 N
White Cement CEM I 52.5 N is characterized by high purity, excellent strength, and optimal workability. With an early strength of at least 20 MPa after 2 days and a final strength of at least 52.5 MPa after 28 days, it guarantees long-lasting load-bearing capacity. The high whiteness (L-value approximately 94–95% on the Hunter scale) and fine grinding (Blaine value approximately 4000 cm²/g) ensure not only an aesthetically pleasing surface but also excellent workability. A low alkali content minimizes unwanted reactions in the concrete, while low values for SO₃ (≤ 4.0%) and chloride content (≤ 0.1%) reduce the risk of reinforcement corrosion. Low shrinkage and high volume stability (Le Chatelier expansion ≤ 10 mm), as well as optimized hydration times (initial setting time ≥ 45 minutes, final setting time approximately 170 minutes), make this white cement the ideal choice for architectural applications, decorative concrete products, precast construction, dry mortar, flooring and road construction, as well as special artistic projects.
