3.1 This test method is used to determine if a freshly mixed refractory castable is of the proper consistency to provide optimum performance. There are times when the manufacturer's specified water content and consistency will purposely not lead to the correct ball in hand but should be used to provide optimum performance.
A product can be described as high-quality if a test measurement ascertains that the desired properties lie within a given tolerance. If the measured values deviate too much, the quality is lower. Many materials, whether natural or artificial, occur in dispersed form (material which does not form a consistent unity but is divided into elements ...
