To inspect the specimen size effect on the castable spalling during rapid drying, the spalling resistance performances and physical performances of green bodies in different sizes and with the castables based on the Alumina bonded with low-cement, ultra-low cement, silica sol, alphabond and MgO-SiO2-H2O, respectively, were studied. It was found that the specimen size effect on the castable spalling was closely relative with the low temperature physical performances. 1) With the green bodies which were denser and stronger, the specimen size effect on the spalling after being heated was bigger; while the initial green body had many pores and the strength was not very big or the initial green body was denser but the strength was ordinary, there was almost no effect. 2) When the specimen size was bigger, the castables with different bonding systems were all easier to be exploded, with the bonding way having not big effect on the castables explosion; while the specimen size was smaller, the hydrated castables were more likely to be exploded. |
