The main chemical components of steel slag are CaO SiO2 Fe2O3 Al2O3 MgO MnO FeO fCaO etc With the difference of raw material smelting technology and steel type the composition of steel slag also changes The chemical composition of converter slag in some Chinese steel mills is shown in table 1
Steel slag is an industrial by product of steel industry It possesses the problem of disposal as waste and is of environmental concern The results were compared with conventional concrete
The chemical composition of the steel slag powder was determined by wavelength dispersive X ray fluorescence spectrometer XRF and the instrument model is ARL Perform X 4200 The mineral composition in different steel slag powders was determined by X ray diffraction XRD The instrument model is D8 discover and the target is Cuk
Studies have shown that the mineral composition of steel slag is similar to that of cement [3 4] and has potential cementation and volcanic ash properties when ground into very fine steel slag powder Due to the large fluctuation of the chemical composition of steel slag as well as the difficulty of grinding and slow hydration its large
In this study steel slag powder SSP and SP by products from manufactured sand were employed with a total dose of less than 30% as a replacement for cement Synthesis of steel slag ceramics chemical composition and crystalline phases of raw materials Int J Miner Metall Mater 22 2015 pp 325 333 /s12613 015 1077 z View
Ladle furnace slag LFS is a by product of a steel plant As the chemical composition and free lime f CaO content of each batch of slag are significantly different it is difficult to use the
Steel slag powder SSP and steel slag fine aggregate SSFA The chemical composition of FA and CA is indicated in Table 1 Superplasticizer SP A superplasticizer additive Sika viscocrete—1681 was obtained from the local market and incorporated to enhance the slump thereby decreasing the quantity of water incorporated into the
Secondly the main chemical composition of steel slag is CaO SiO 2 and Al 2 O 3 which is very similar to the composition of cement and theoretically has a specific cementitious activity [9] Therefore steel slag can be considered an admixture in concrete to reduce cement consumption and further reduce cement production
