heal.abstract	Structural properties, such as apparent density, true density, porosity and shrinkage of resin bonded bauxite specimens, were measured. Different bauxite grain sizes, resin contents, moulding pressures and firing temperatures were selected for preparing the specimens. Simple mathematical models were used to correlate the examined properties as functions of production conditions and materials' characteristics. The proposed models were fitted on the experimental data and parameters were estimated. After data analysis, it was found that low porosity specimens are produced using high materials grain size and moulding pressure, along with firing at higher temperatures. True density did not appear to indicate significant changes for all the above parameters. Shrinkage is mainly affected by firing temperature but does not depend on moulding pressure. Increase in firing temperature increases shrinkage due to higher sintering, while high grain size leads to specimens with low shrinkage. Finally, SEM was used to observe the above mentioned phenomena. © W. S. Maney & Son Ltd. 2011.	en
