RR Super Power 90
RR Super Power 90 is a free flow castable . it is a cement free castable and giving enhanced and refractory cost.
RR super power-90 is supplied with binder Liquid as it is gel bonded castable.
The ratio of Concrete to Binder liquid is l 10:1 i.e. 10% of binder Liquid added to the weight of castable.
It set normally within 8-10 hours time at 35 C.
- Advantages
- Specification
- RR SP-90 has a best thermal Shock resistant due to strong multiple formation at elevated temperatures.
- RR Sp-90 retains four times higher Strength than low cement castable.
- RR SP-90 requires least vibrations as it is self folow or free flow.
- RR SP-90 increase Strength with increase temperature. it is a unique property.
