The question of how much the proportion accounted for cement in castable refractory

In the use of castable refractories, cement is added in a certain proportion, if not add the proportion of refractory castable, whole effect will be affected to a certain extent, then to tell you in the cement castable refractory in the percentage of problems:

Using cement as binder for refractory pouring material has the advantages of simple construction, wide application range and so become refractory castable most customers Pro gaze now. Refractory castable cement is the main factor to determine the initial strength of the castable refractory, so many customers that cement castable refractory in the greater proportion of the strength of the castable is better! Now I can clearly tell you: This is not right. Because if the content of cement refractory castables inside is too high, it is easy to cause the reaction in later add end mixture hardening when you need to add a certain amount of water, this will make the castable formation setting and hardening strength when certain, so we can call this kind of castable refractory for hydraulic. But there is one thing we should know is the main point to decide the strength of cement castable refractories, if the volume of cement did not add to or less will cause the strength of the castable is not ideal. But its refractory degree is not very high, so we should pay attention to the use of in room temperature when in use, and may use less cement. But really need to increase the compactness of cement or construction must be used, we can choose the refractory powder doped in to. So we in the pouring material inside when using cement must be careful not to use too much.
