Many people can t tell the difference between refractory cement refractory castable and refractory mortar. Simply speaking refractory cement is used as binder of refractory castable sometimes it is used as a binder of refractory mortar and it is rarely used alone. 3. Economy. Since the quality depends mainly on the water to cement ratio the water requirement should be minimized to reduce the cement requirement (and thus reduce the cost). Take these steps to reduce the water and cement requirements use the stiffest mix possible use the largest size aggregate practical for the job.
