The Characterization of Steel Slag by Alkali Activation
OALib, 2017 This paper presents a characterization analysis of alkali-activated steel slag. The effect ratio of steel slag and ferronickel slag which are the precursor materials on the compressive strength of the alkali-activated materials was investigated. The combination of sodium hydroxide solution of 15 moles concentration and sodium silicate was used as an ...

CARBONATION RESISTANCE OF SLAG MORTARS ACTIVATED BY DIFFERENT ALKALI ACTIVATORS
Turkish Journal of Engineering, 2017 In this study, the carbonation depths of slag mortars activated by sodium silicate (water glass), sodium hydroxide and sodium carbonate were investigated and the results were compared to those of control mortar with CEM I 42.5 R normal Portland cement. In the mixture, the sand/binder ratio was 2.75 and the water/binder ratio was 0.50. Na concentrations
