Aluminous and high-alumina cements
Aluminous cement is a binder for heat-resistant and refractory castables. High-alumina cements are used for castables with a higher operating temperature.
All grades are made to GOST 969 "Aluminous and high-alumina cements". The number in the grade is the compressive strength after 3 days, MPa.
Grades and types
Aluminous cement ГЦ-40
To GOST 969. Aluminous cement is a binder for heat-resistant castables and mortars. 40 is the compressive strength after 3 days, MPa. It gains strength quickly, so the lining can be put into service sooner.
Aluminous cement ГЦ-50
To GOST 969. Aluminous cement with increased strength: 50 MPa compressive strength after 3 days. Used when higher strength requirements apply to the castable or mortar.
High-alumina cement ВГЦ-I-35
To GOST 969. High-alumina cement type I; 35 is the compressive strength after 3 days, MPa. Contains more alumina than ГЦ — for refractory castables with a high operating temperature.
High-alumina cement ВГЦ-II-25
To GOST 969. High-alumina cement type II; 25 is the compressive strength after 3 days, MPa. For refractory castables with a high operating temperature; the cement type is chosen according to the castable recipe.

How to choose a grade
Aluminous cement ГЦ is a binder for heat-resistant castables and mortars. High-alumina ВГЦ contains more alumina and is needed for refractory castables with a higher operating temperature.
Within a type, the grade is chosen by the required strength: ГЦ-50 is stronger than ГЦ-40.
Frequently asked questions
How does ГЦ differ from ВГЦ?
The alumina content: it is higher in high-alumina ВГЦ, so castable based on it withstands higher temperatures. ГЦ is used for heat-resistant castables and mortars.
What does the number in the grade ГЦ-40 mean?
The compressive strength after 3 days, MPa (GOST 969). The Roman numeral in ВГЦ-I and ВГЦ-II is the type of high-alumina cement.
