Preparation of Porous and Dense Bulk Samples in Calcium Magnesium Silicate Systems Using Steel Slag and Different Additive By Conventional Sintering Method

In order to obtain the bulk brick-like samples, the mixture of steel slag, and sintering aid additive (likedolomite, glass, perlite borax and phosphate sodium) were sintered at 1100°c for 2 minutes. the flatand bloated surface appearances were obtained. the bulk densities of final sintered composites ranged 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. the final phase as detected by xrd according was calcium magnesium silicate
