high alumina cement the goods has excellent high-temerperature good anti-corrosion performance
high alumina 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
The company's production of aluminate cement CA-50 series based on the development of cement hydration and the relative intensity of the physical strength to be the value of the product into different grades, so that customers according to their demand for the product and the use of conditions to choose. Meanwhile, through the production process of the optimization of product performance so that it can adapt to both the monolithic refractories different construction methods (such as: casting, injection), also can meet a variety of castable formula system, such as: the traditional combination of high alumina cement castables and medium-cement castables, the performance of the construction made by the different requirements.
This series of product does not contain any additives to ensure product suitability and stability.
