Jul 27, 2021· This paper investigates the effects of using Ground Granulated Blast Furnace Slag (GGBFS), Lead Slag (LS) and Zinc Slag (ZS) as replacement for sand on the strength of concrete.
Ground Granulated Blast Furnace Slag (GGBS) GGBS is mainly used as a partial replacement of cement in concrete. When added as an admixture to concrete, it acts as a stabilising agent and improves the quality of concrete. In the production of ready-mixed concrete, GGBS replaces a substantial portion of the Portland cement component, generally ...
metakaolin [12], different types of slag like ladle furnace slag, ground granulated blast furnace slag etc. For geopolymer mortar having 50 mm cube size, suggested optimum curing temperature of 60°C. The given recommendation is founded on the assumption that a smaller cube has a higher surface-area-to-volume ratio than a larger cube.
Ground-granulated blast-furnace slag (GGBS) is a supplementary cementitious material used in concrete and is produced by drying & grinding of Granulated blast furnace slag into a fine powder. GGBS's intrinsic properties contribute towards manufacturing sustainable concrete with higher compressive strength, reduced permeability & resistance to ...
Blast furnace slag is nonreactive in a high alkali environment, such as concrete and soils. Blast furnace slag concrete can be reliably pumped when the slag is supplied to the ready-mix production in a saturated condition. Use of the cementatious properties of ground granulated blast furnace (GGBF) slag was reported as early as 1774. GGBF slag ...
Ground Granulated Blast furnace Slag (GGBFS) is made by quenching molten blast furnace slag (a by product of iron and steel making) in water to produce a glassy granular product that is then dried and ground into a fine powder GGBFS .It consists mainly of calcium and aluminum silicates and has a chemical composition similar to these respective natural minerals and to hydrated Portland cement.
Ground granulated blast furnace slag (GGBS) was employed as the main component of an alternative binder. Ground agricultural gypsum and construction-grade hydrated lime were used as activators in the proportions of 0.88:0.10:0.02 (GGBS:gypsum:lime) by mass as previously discussed (Oliveira et al., 1999).Sisal (Agave sisalana) field by-product was selected from a variety of Brazilian fibrous ...

ABSTRACT: Both reactive MgO and CaO are alternative activators for ground granulated blast furnace slag (GGBS). In this study natural dolomite, as a source of MgO and CaO, was calcined at 800°C (D800) and 1000°C (D1000) under air. The activation of GGBS with the calcined dolomites
May 26, 2016· • GGBS means the ground granulated blast furnace slag is a by-product of the manufacturing of pig iron. • Iron ore, coke and Lime-stone are fed into the furnace and the resulting molten slag floats above the molten iron at a temperature of about 1500oC to 1600oC.
Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.
The aspect of this work not employed before was the use of the cutter soil mixing to form a safe zone through which to telescope the d-wall shaft similar to the approach a GI contractor would adopt if undertaken "clean drilling" methods. The use of 80% Ground Granulated Blastfurnace Slag (GGBS) within the cementitious grout mix ensured that ...
Thus finally it is cost effective solution in current competitive market. Granulated slag obtained from blast furnace slag is wet and coarse in nature and can not be useful directly. So drying and grinding process are carried out to make it useful.
procured from Sona Alloys Pvt. Ltd. Ground granulated blast furnace slag is the by-product of smelting ore to purify metals. Slag has pozzolanic reaction which allows the increase of compressive strength. The physical properties of GGBS are presented in Table 1 as per IS 4031-1988 (IS 4031,1988).
