Effect of curing time on the volume stability of corundum
The results indicate that the volume stability of castables is greatly improved by increasing curing time from 0.5 days to 6 days after firing at 1600 °C. This can be attributed to two main reasons. First the improvement in migration of CaO through extending curing time favors more uniform distribution of
