Currently, almost all blast furnace slag is utilized for various purposes, such as cement making, road construction, fertilizer, etc. In some countries, including Indonesia, steelmaking slag is categorized as hazardous and toxic waste. However, slag can be used as raw material for the other purposes.
Uses of BlastFurnace Slag Cement. Used in ready mix concrete plants. Used for structures meant for water retaining such as retaining wall, rivers, ports, tunnels for improvement in impermeability. Used in mass concreting works such as dams, foundations which require low heat of hydration.
Slag cement should not be used in the concrete projects of which the impermeability is very important. 6 Good Heat Durability. Slag cement has good heat durability that can be used to prepare heatresistant concrete because it contains a little calcium hydroxide after hardening and it
Indonesia: Semen Indonesia has launched a new slag cement product under the brand Maxstrength Cement. The cement producer said it was the first Portland Slag cement produced in the country. The company can producer 1500t/day of the slag cement and it is intended for use in large scale infrastructure projects that require high flexural

Slag Used In The Cement Indonesia The influence of nickel slag aggregate AIP Portland cement is the most dominant binder to produce pasta composite and Vale Steel Slag Crusher In Indonesia is slag used in the cement indonesia From large primary jaw crusher and impact crusher to cone crusher and VSI series for secondary or tertiary stone .
Indonesian Cement Association''s (ASI) data show that domestic cement sales volumes rose by 7% yearonyear in May 2017 to Sales volumes for January to May 2017 increased by 4% to Fitch has attributed this growth to a 13% growth in sales of bulk cement, which is used mainly for infrastructurerelated developments.
#0183;#32;The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: Blastfurnace slagThe nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast
Nov 21, 2020#0183;#32;Slag cement has actually been used in concrete projects in the United States for over a century. Its earliest use was documented in 1774, when it was combined with slaked lime and used as a mortar . This cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slaglime cement.

Taken from a Material Safety Data Sheet for the primary material used in Orcems Green Cement products. GBFS. Section 2 Hazards Identification Granulated Blast Furnace Slag is hazardous according to the criteria specified in European Directives 67/548/EEC, EU directive 1999/45/EC and OSHA Hazard Communication Standard 29 CFR
27 #0183;#32;Usage and Applications. 1. GBFS as an Aggregate. GBFS can be used like sand as a
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing
What is slag cement
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial byproduct of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield
2. Steelslag can be used to produce energysaving cement by cogrinding with OPC clinker and blastfurnace slag. In such preparations OPC clinker is about 1530%, steelslag around 3040% and blastfurnace slag is around 4050%. 3. Producing energysaving steelslag cement can save energy, natural resources and cut GHG emissions by around
Coarse BOF slag aggregates, which underwent three years of aging before using, were used in SMA mix design (Wu, Xue, Ye, amp; Chen, 2007; Xie et al., 2012; Xue, Wu, Hou, amp; Zha, 2006).The percentages of each fraction used to replace basalt stone aggregate are given in Table properties of the aggregate used are shown in Table
#0183;#32;Slag is commonly used to make cement. Common components of slag include the oxides of silicon, aluminum, and magnesium, as well as sulfur, which is always present. It also contains phosphorous, calcium, ash, remnants of flux materials such as limestone, and remainders of chemical reactions between the metal and the furnace lining .
Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.
Slag cement use can be traced to the 1700s when the material was combined with lime to make mortars. The first United States production was in 1896. Until the 1950s, granulated slag was used in the manufacture of blended portland cements, or as raw feedstock to make cement clinker.
Indonesia: Fajar Harry Sampurno, the StateOwned Enterprises (SOE) Ministry''s undersecretary for mining, strategic industries and media affairs, says that the Environment and Forestry Ministry will issue rules stating that mineral waste such as slags resulting from processing nickel and copper ores could be used as raw material for the production of bricks, asphalt, concrete and cement.
