Good day.
Would appreciate if anybody could advise what happened to our transition floor refractory which we found wet/moist and found some spalling and cracks. The transition floor units have not been installed yet and is still our storage waiting for delivery advise. We also found some moisture and water dripping on some parts of the refractory. After some hammer test. we noticed a "dull" sound. Does this mean we need to repair the refractory? do we need to replace the TR bricks underneath as well? pls advise?
