ABSTRACT
Abstract The influence of several mineral admixtures on the transition zone in concrete has been studied using the Grandet-Ollivier method. By substituting cement with either condensed silica fume, ground granulated blast furnace slag, or rice husk ash it is shown to that a smaller transition zone and a lower concentration of calcium hydroxide (CH) crystals in the transition zone. None of the mineral admixtures had a significant influence on the degree of preferred orientation of CH crystals in the transition zone. Keywords: Condensed Silica Fume, Slag, Rice Husk Ash, Calcium Hydroxide, Preferred Orientation, Concentration Intensity.
