Castables with vibra- flow values above approximately 60 are placeable by vibration.
In table 4 are given the resultant flow values of the mixes presented in Table 2 and 3.
Firstly, the very good match in flow values of the two castables and secondly, the dependence of the flow on the supernnes.
Addition of citric icid (0.03%) to the 100vol% reactive alumina composition seemingly increases work time although the effect is somewhat questionable due to an overall very low free flow value for this composition.
Figure 7 shows the same castables as Figure 6, this time the vibra flow values.
