Micro-Powder in Refractory Castables ArchivesRongsheng
· The basic mechanism of micro-powder in refractory castables is filling and lubrication.The micro powder can be used to fill the gap between aggregate and powder reducing the amount of water used. After the molded body removes water there are fewer holes left which can increase the bulk density and reduce the apparent porosity.
