How much water is added per kilogram of castable

The reference amount of water added for ordinary refractory castables is 8%-10%. When actually adding water, you can add water according to the principle of “small and many times” (control the time well, and the mixing time of the castable should not be too long). It means that the amount of water added is too small; if the ball-shaped castable flows down from the fingers after holding the dough, it indicates that the amount of water added is large; if the ball-shaped castable does not disperse or flow out, it indicates that the amount of water added is small.
