RC cement is made from mixing selected limestone and bauxite ,calcined to partly or fully melted in roatry kiln, the clinkers are ground to cement. With the content of Al2O3 up to 40-65%, the main mineralogy is CA, which can ensure high refractoriness, and the temperature suggested for application is up to 1400 ℃.
Application Field
APPLICATION
With good properties, Aluminiate Cements are widely used in following fields:
- Preparation of monolithic refractories;
- Preparation of gypsum alumina cement expansive cement, self-stressing and other special purposes;
- Building, maintaing, repairing construction with anti-erosion against sulphates, and other construction projects with special needs.

MSDS
MSDS
A safety data sheet (SDS), material safety data sheet (MSDS), or product safety data sheet (PSDS) is an important component of product stewardship, occupational safety and health, and spill-handling procedures. SDS formats can vary from source to source within a country depending on national requirements.
SDSs are a widely used system for cataloging information on chemicals, chemical compounds, and chemical mixtures. SDS information may include instructions for the safe use and potential hazards associated with a particular material or product. The SDS should be available for reference in the area where the chemicals are being stored or in use.
Our team is in dedicate and professional position to provide above information for our customers and related operators to properly deal with what we supply to all over the world. You are welcome to contact us to get such information or data, and please click MSDS or just address support@unitshine.com.
