Production of Refractory Binding Material for Cement Kiln

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.
