IRON AND STEEL SLAG Events, Trends, and Issues: The amount of iron and steel slag consumed increased by a small amount. While iron slag consumption overall stayed about the same, the amount of iron slag that was expanded or granulated increased. This was due to slag being used in greater quantities as a replacement for portland cement.

Study of Radioactive Characteristics of Cement Pastes Blended with GGBFS. Abstract This paper reports an experimental study carried out to investigate the effects of ground granulated blast furnace slag (GGBFS) on radiation attenuation and mechanical properties of blended cements. Five cement mixtures were prepared with 0%, 10%, 15%,...
The use of slag in different fields of application, for example the granulated BF slag (GBFS) as substitute for cement and for clinker in cement and the steelmaking slag for soil conditioning, can allow the reduction of the tonnages of CO2 emission.
Steel slag is produced in large quantities during the steelmaking operations which utilize Electric Arc Furnaces (EAF). Steel slag can also be produced by smelting iron ore in the Basic Oxygen Furnace (BOF). Steel slag can be used in the construction industry as aggregates in .
When cement is mixed with water, it can bind sand and gravel into a hard, solid plant and fed into a crusher, which crushes the boulders into marblesize piec Concrete is a composite material consisting of aggregate (gravel and sand), Slaglime cements: Ground granulated blast furnace slag is not hydraulic on its. Contact Supplier
Nowadays the use of slag in concrete, either as a constituent of cement or as a mineral admixture, is widespread. The granulated blast furnace slag has low resistivity, and so can be used as an agent for reducing resistance to grounding.
tance, shear strength as well as the cost. The aim of this study was to examine the effect of groundgranulated blast furnace slag (GGBFS) and basic oxygen furnace slag (BOFS) on the mechanical properties of RCCP, using the tests of compressive strength and indirect tensile strength.
(GGBFS): Hydraulic cement formed when granulated blastfurnace slag is ground to a suitable fineness commonly referred to as slag cement, or India, annual productions of pig iron is 7080 million tons and corresponding blast furnace slag are about 2124 million tons. The blast furnace slag could be used for the cement raw material, the roadbed material, the mineral admixture for concrete and .
Concrete Produced by SteelMaking Slag (Basic Oxygen Furnace) Addition in Portland Cement Hasan Alanyali,* Mustafa C¸o¨l, Muharrem Yilmaz, and S¸adi Karago¨z Faculty of Engineering, Kocaeli University, IzmitKocaeli, Turkey A steelmaking slag (basic oxygen furnace) obtained from the Kardemir Steelworks was modified to be used as a clinker
This study investigates the feasibility of cofiring fly ashes from different boilers, circulating fluidized beds (CFB) or stokers as a sustainable material in alkali activators for ground granulated blastfurnace slag (GGBS). The mixture ratio of GGBS and cofiring fly ashes is 1:1 by weight. The results indicate that only CF fly ash of CFB boilers can effectively stimulate the potential ...

workability of self compacting concrete with ground granulated blast furnace slag up to 30% replacement is very good [16]. A new mix design methodology for self compacting concrete with ground granulated blast furnace slag (GGBFS) as replacement material for cement is proposed [17]. According to this method they
The study shows that while there is a marginal reduction in the early age strength of the Portland Slag Cement mortar, the later age strength does not suffer by replacing up to 20% of Ground Granulated Blast Furnace Slag (GGBFS) by EAF slag.
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 readymix 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 .
This paper examines the possibility of using groundgranulated blastfurnace slag (GGBFS) as a partial replacement of filler in polymer grout. In this study, river sand was replaced by GGBFS at levels of 0 (control), 10, 20, and 30% by weight.

Background information ... arc rotary furnace. It was found from their studies that the recovery of aluminium is about 10% through this process.
Portland blast furnace is a mixture of Portland cement and granulated slag which constitute about 65% of the mixture according to BS 146:1958 [3]. Portland blast furnace cement is similar in physical properties to ordinary Portland cement, and the British Standard for the two is .
Reactive powder concrete (RPC) is an ultra high strength cementbased material. Cement and silica fume (SF) content of RPC are generally rather high compared to the conventional concrete. The aim of this study is to decrease the cement and SF content of RPC using with fly ash (FA) and/or ground granulated blast furnace slag (GGBFS).
Since ground granulated blast furnace slag (GGBFS) is a marketed commodity with no excess supply in the United States, reducing slag use is an economical means to produce durable concrete.
