A new mineral binder for No Cement Castable (NCC) and its adaptability to specific working and hardening times will be discussed in this paper. Commonly, setting behavior of refractory castables can vary in different ambient temperatures, depending on the binding type used due to the different reactions involved (hydraulic, chemical, gelling-coagulating, polymerization,...). Also, at a given temperature, levers are needed to adjust the working and hardening time to specific applications and formulations. Due to different reaction kinetics at different ambient temperatures for a given castable binder system, usually one experiences an excessively long setting time at low temperatures, while inversely, having a very short workability and setting at high temperatures. This article will first show the impact of curing temperature in the range of 5-35°C on a castables bonded with the new NCC-mineral powder binder prototype, in comparison with other binders like colloidal silica by measuring rheology, ultrasonic profile and green/dried mechanical strength of a bauxite reference castable. In the second part it will be investigated how the usage of common accelerators/retardants interact with this new binder system. Solutions will be explored that could be used as a lever to create sufficient robustness to curing conditions and to help formulators to adjust their recipes to specific working and demolding time requirements.
