Low cement (LCC) or deflocculated castable technology has been widely adopted in the past decades due to the improved thermomechanical properties and corrosion resistance that these castables display in service. These improvements in performance have been made possible by the increased sophistication of refractory formulations and improvements in installation methods. In particular, the use of mathematical models for calculating precise grain distributions, as well as the use of fine particle sized fillers of alumina and microsilica allow for the development of very dense castable structures with excellent properties in a wide range of refractory applications. These dense structures also rely on high performance deflocculants and dispersing agents in order to fluidify the castables with a minimum amount of water.
