Scope of application:
Because of its Ultra high strength and 28 days compressive strength can reach more than 100MPa,its application scopes are projects with special requirements on strength, such as treasury, nuclear power plants, special projects with a service life of more than 100 years.
Dosage, storage and durability is same with CGM-T70.
