Note 1 The material described in this specification may be used for blending with portland cement to produce a cement meeting the requirements of Specification C 595 or as a separate ...
As the primary raw material, ground granulated blastfurnace slag produced by Isfahan Steel Company was used. Specific weight and Blaine of GGBFS were g/cm 3 and 4500 cm 2 /g, respectively. The chemical composition of slag by performing the XRF test is shown in Table 1.
Slag. Groundgranulated blastfurnace slag (GGBFS) is produced by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder. When added to concrete, GGBFS enhances a range of performance characteristics such as the reduction of ...
Wood ash was incorporated as a 0 wt%, 10 wt% and 20 wt% partial replacement for ground granulated blast furnace slag (GGBFS). The wood ashes were ground in a planetary ball mill for 10 and 20 min. Sodium silicate (Na2SiO3), sodium carbonate (Na2CO3), and sodium hydroxide (NaOH) were used as alkali activators.
The ground granulated blast furnace slag was added to beam concrete and the stiffness of specimens with 50% and 70% content is 10% and 4% higher than that without ground granulated blast furnace slag, but the stiffness of specimens without ground granulated blast furnace slag is 16% higher than that of specimens with 90% content.
in Germany a slaglime cement was commercially produced. By 1901 the manufacture of "Eisenportlandzement" containing maximum 30% of ground granulated blastfurnace slag (ggbfs) became accepted and in 1907, the first "Hochofenzement" with up to 85% ggbfs content was produced (MoranvilleRegourd 1998; Smolczyk 1978).
Introduction. Granulated blast furnace slag (abbreviated GBFS) is an industrial solid waste generated in the steelmaking process [1], [2]. It is rich in CaO, SiO 2, Al 2 O 3 in chemical compositions and the mineral phases of GBFS are mainly composed of glass phases [3], [4]. Based on its chemical and mineral compositions, GBFS has a good hydration activity [5], [6], [7], [8].
