What is slag cement
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
GGBFS as a Cement Replacement GGBFS/GGBS or Slag Cement Slag consists mainly of calcium, aluminium and silicate has a chemical composition similar to these respective natural mineral materials and to hydrated Portland Cement. It is often mixed with fresh Portland Cement powder in the manufacture of concrete, mortars, grouts etc.
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.
#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 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.
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
The cement uses only 1530% of OPC clinker, 3040% of steelslag and 4050% of blastfurnace slag (BFS), allowing for great reductions in GHG emissions, consumption of natural resources and energy use by between 70% and 85%. The characteristics of steelslag as a supplementary cementitious material are also discussed.

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
George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016. Slag cement use for special applications. Slag cements disappeared from the market mainly because they presented relatively low mechanical resistance at first aging and failed to present other competitive advantages concerning cement other than lowering the price.
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.

#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
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 strength, such as bridges or road flyovers.
Spesifikasi semen slag untuk digunakan dalam beton dan Standar Nasional Indonesia tentang Spesifikasi semen slag untuk digunakan dalam beton dan mortar merupakan adopsi identik dari ASTM C 10, Standard specification for slag cement for use in concrete and mortars dan merupakan revisi SNI 2000, digunakan sebagai standar untuk menetapkan tiga tingkat kekuatan semen slag untuk digunakan
Slag is a byproduct of steel production and is similar in character to volcanic rocks such as basalt and granite. Slag is primarily used in the cement and construction industries, and largely in
Slag happens when iron ore is melted. The molten iron sinks to the bottom, while the slag will float on the top of the iron. See the diagram below: Another difference between slag and fly ash is that while fly ash will rarely surpass 35% of the cement content, slag can substitute 50% of the cement content, or even higher for different applications.
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.
