Effect of Chemical Composition on the Latent Hydraulic Activity of Blast Furnace Slag
Glasses showing the composition of blast furnace slag were made in the laboratory, and the effect of the chemical composition on the latent hydraulic activity of the slags was examined. The latent hydraulicity was greatly influenced by the composition change, the optimal characteristic of the hydraulicity was achieved at the slag composition of 47CaO:20Al2O3:33SiO2. The content of CaO and Al2O3 were not equivalent to the hydraulic activity of the slags as the b-formula (KS L 5210) indicates. Good latent hydraulicity was shown when Al2O3 was richly contained at the high (CaO+Al2O3):SiO ratio, while the more the MgO content was, the more negative the result turned out.
Key words: Laboratory-made slag, Chemical composition, Latent hydraulic activity, Hydraulicity
