Regardless of the installation method being deployed in order to successfully install refractory materials, generally speaking, monolithic refractory installations share one common step, the addition of water. Whether the water is added in a large paddle mixer prior to being vibration cast, pumped, or shot-creted, at a nozzle prior to being gunned, or in a pail prior to being hand cast, this step has wide-ranging impacts on several aspects of the end result.Would you like to know more kinds of refractory products?welcome to come to our factory to view more refractory products.

The water content can easily be taken for granted. At times, it is tempting to add additional water relative to what is called for on a product’s mixing and use instructions in order to get the material to flow better, avoid voids, or extend the workability time. At other times, it can be seen as beneficial to reduce the water content with the intention of improving physical properties or expediting set times. While, the introduction of additional water is a far more common offense, in reality, introducing water to a refractory mix that is outside the parameters set by the material manufacturer can have the following detrimental impacts on the finished products:

Dry-out – Improper mixing of monolithic refractories can cause significant problems during the refractory dry-out process. More water leaving the lining can lead to excess steam and pressure causing linings to crack, spall, or even explode during the dry-out. Furthermore, since the materials were improperly mixed in the first place, the physical properties associated with the material are likely reduced which compounds the problems potentially experienced during the dry-out period.
