What is the difference between refractory plastic and ramming material?

Refractory plastics and refractory ramming materials are unshaped refractory materials with different ramming or ramming construction methods.

Due to the different binders, its plasticity or working performance is different. When the plasticity index is greater than 15, it is called plastic, and when it is less than 15, it is called ramming material.

The dry vibrating material has no plasticity, but it is usually constructed by ramming. Except for the different molding methods, the performance testing method of plastic and ramming material is basically the same as that of castable.

In short, the difference between plastic and ramming material is: when the index is greater than 15, it is plastic, and when the index is less than 15, it is ramming material.
