Calcium Aluminate Cement

The goods has execllent high-temperature service supply calcium aluminate cement

The product uses superior alumina powder and calcium oxide as its raw materials. Its production process is as follows: First, the raw materials are weighed and homogenized according to a certain proportion. Then, the homogenized materials are sent into smelting workshop and smelted there. Next, the processed materials are crushed and grinded. Fourth, we get the finished product and pack it. Featured by its stable quality, low water requirement, fast and full hydration and high initial strength, calcium aluminate cement is used as the fine binding material in the process of manufacturing various high-class shapeless refractory. Calcium aluminate cement is also used as the gelling agent in the make-up of low cement, ultra-low-cement castable, self-flowing castable, pump feeding and gunning refractory etc. In addition, the initial setting time of calcium aluminate cement can be adjusted as per the request of clients, including quick-setting, medium, slow setting and special slow settin g etc.
