The Use of Microsilica in Refractory Castables'
The technology of preparing refractory castables is presented focusing on the use of microsilica.
Predictive flow control by the use of particle size distribution and set time control at high temperatures are the main aspects of the refractory castable technology that is presented in this paper.
Once properly dispersed, one important property is to reduce the cement content of refractory castables due to the small particle size of microsilica.
According to the patents by Prost and Lafarge, the cement content of refractory castables may be reduced to approximately 1% by the use of carefully graded particles afllhe" way down to sub-micron sizes.
