INTRODUCTIONCassava starch is a substance with high colour(whiteness) low dirt and fiber content thatpossess a strong firm, good water holdingproperties and stable viscosity (Frost et al, 1997).The word refractory means hard to fuse. It is amaterial which can withstand higher temperature,resist action of corrosive liquids and dust – ladencurrent of hot gases. This refractory materialconsist usually a mixture of oxides obtained fromnaturally occurring materials capable of resistingload at higher temperature (Chester, 1986).
AIMS AND OBJECTIVESThis project is aimed at investigating suitability ofcassava starch as a binder for the production ofrefractory bricks.Specifically, this research will • Produce refractory bricks 1 using cassava starch as the binder; • Determine the effectiveness of T 2 producing a refractory bricks using cassava starch as the binder; and • Determine some of the 3 properties of the refractory produced.
SCOPE OF THE STUDYThis study involves the investigation of the suitability ofcassava starch as a binder for production of refractorybricks and as such it entails:Obtaining cassava starch and the refractory material(Calcium Oxide);Production of refractory bricks from cassava starch;Ascertaining its suitability by carrying out physicaltest analysis like its porosity, permeability, crushingstrength, abrasion resistance, erosion resistance andlinear shrinkage etc.
PROPOSED METHODOLOGYThe proposed methodologies are:•Sample Collection;•Crushing and Grinding;•Sieving Analysis;•Pre – treatment;•Mixing;•Moulding;•Drying;•Firing;•Drop Number Test; and•Porosity Test.
JUSTIFICATION OF THE STUDYBecause of the demand and cost of refractory materials for Nigeriaindustries to thrive better, there is a need to source for refractorybinders’ locally like the cassava starch to reduce the cost of obtainingrefractory for such process. This then calls for a research toinvestigate the suitability of cassava starch as binder for productionof refractory bricks. It will also at the end of this research revealweather cassava starch can act as a good binder or otherwise.The choice of methodology is based on the fact that cassava starch isa substance with high colour (whiteness), low dirt and fiber contentthat possess a strong firm, good water holding properties and stableviscosity which will at the end of this research weather cassava canact as a good binder or otherwise
PROGRESS MADEThe chapter one and two have been writtenand submitted to the supervisors. Sampleshas been collected and is being prepared forthe production of refractory bricks usingcassava starch as a binder.
