The color hardener can be applied using one of two procedures; integral ...
White Portland cement differs physically from gray cement only in terms of its color. Its setting behavior and strength development are essentially the same as that expected in gray cement, and it meets standard specifications such as ASTM C 150 and EN 197. In practice, because much white cement is used in pre-cast concrete products, it is ...
The higher pressure of 10,000 kPa (1,500 psi) permits a thicker pigment layer to be embedded into the cement layer. The pigment layer is usually 3–4 mm (0.12–0.16 in) thick. Another difference is the quality of the pigments used. High-quality producers use mineral-based pigments only. Non-mineral-based pigments fade with age.
Strontium aluminate cement can be used as refractory structural material. It can be prepared by sintering of a blend of strontium oxide or strontium carbonate with alumina in a roughly equimolar ratio at about 1500 °C. It can be used as a cement for refractory concrete for temperatures up to 2000 °C as well as for radiation shielding. The use ...
