| Abstract Scope |
Refractory castables are susceptible to degradation of the hydraulic binders and superplasticizers over time. The hydroscopic nature of these materials makes them prone to deterioration before use when exposed to environmental moisture either through extended storage or humidity. The flow, set time and physical properties can all be negatively impacted as castables age. The degradation in these properties can cause installation and potentially service performance problems. There are several measures that can be taken to minimize the effects of aging including controlling raw materials, product design, packaging and storage. Both real-time and accelerated aging tests will demonstrate the variables of aging. Different binder types will be compared for their effect on shelf life stability. The effect of paper versus plastic packaging and the proper storage conditions will be reviewed. |
