high Aluminate Cement

1.execllent high-temerperature 2.high intensity 3.good anti-corrosion performance

  High-Aluminate Cement

Aluminate cement products for the alumina content of 50% -60% of the cement matrix.

Aluminate cement CA-50 series products, the main mineral phase composition of CA-phase (a calcium aluminum acid. 2 aluminum acid a calcium). Therefore, not only products with a relatively high temperature use of performance, but at the same time have a reasonable and stable hydration of the performance, rapid growth in outstanding physical strength properties
