Production of Refractory Binding Material for Cement Kiln

Abstract

This paper investigates the production of refractory binding material for lining
bricks in the cement kiln using locally available materials. Titrimetric method was used to
estimate the main constituents of imported refractory orylex mortar and local river sand. It
was observed that silicon fire-clay, fire clay and high alumina refractory binder used in
binding bricks at the calcining and safety zones of cement kiln have related constituents as
the local river sand and clays. The local refractory mortar was produced by subjecting
milled local river sand to heat with subsequent reduction of the sinter size. This is then
mixed with prepared sodium silicate solution of various concentrations to give a locally
produced composite binder. The product was then tested for stability in electric furnace at
10000C. The project thus highlighted some possibilities of production of local refractory
binding material from locally available raw material.
