Application areas | GNPGraystar’s Silica Fume is perfect for use in refractory castables, including low and medium cement, vibratables, and self-flow castables. Use of Silica Fume improves the mechanical properties (MOR, CCS, creep,etc.) of castables by acting as a flow agent of water required to place refractory castable mix. | |
