PREPARATION OF POROUS an‎d DENSE BULK SAMPLES IN CALCIUM MAGNESIUM SILICATE SYSTEMS USING STEEL SLAG an‎d DIFFERENT ADDITIVE BY CONVENTIONAL SINTERING METHOD (TECHNICAL NOTE)

In order to obtain the bulk brick like samples, the mixture of steel slag, and sintering aid additive (like dolomite, glass, perlite, borax and phosphate sodium) were sintered at 1100°C for 2 minute. The flat and bloated surface appearances were obtained. The bulk densities of final sintered composites were from 1.3 to 2.41 g/cm3 and total porosities were from 15 to 40%. The bending strengths varied from 5.5 to 15.9 Mpa.
