Abstract
This work presents the characterization of slag cements produced by mixtures with modified steel slags. Chemical analysis and mineralogical characterization are shown in Part 1 in this Congress. The physical-mechanical characterizations of cements were done after the addition of slags in Ordinary Portland cement. The cement hydration was analyzed by isothermal calorimetry, thermogravimetry and X-ray diffraction in cement paste. Compressive strengths of cements were satisfactory when compared with normal slag Portland cement. The compressive strength, soundness and autoclave expansion of PSC contained modified slags indicate the application viability as supplementary cement material.
