Aging resistance is a requirement additives have to fulfil in refractory castables 1 . However castable aging limits the storage time of dry mixed and packed castables. Therefore a shelf life is given by the castable suppliers. For modern low and ultra-low cement castables a shelf (LCC s) and ultralow cement castables (ULCC s) have grown significantly over the last decade. This is due to the CaO present in the cement which leads to decline in the high-temperature properties. Conventional castables consist 15-30 CAC the amount being necessary to achieve satisfactory strength at low and intermediate temperatures.
