A new generation of deflocculants and microsilica used to modify the properties of a conventional refractory castable based on a chamotte filler

Abstract

An efficient deflocculant for a conventional refractory castable based on a chamotte filler is proposed. Aparticle distribution analysis is given for a dry castable mix containing microsilica, and the physicomechanical properties of the conventional refractory castable modified with microsilica and Castament FS40 polycarboxylate deflocculant are studied.
