Portland blast-furnace slag cement definition is - a cement produced by intimately intergrinding a mixture of portland cement clinker and granulated blast-furnace slag in widely varying proportions.
Blast-furnace slag is used in making-four classes of cement— Puzzolan, or ordinary slag cement, usually simply called slag cement. Slag Portland cement, which may be a true Portland cement. Iron cement or Eisen cement, which is a mixture of slag and ordinary Portland cement. Several special varieties of cement. Slag Cement
Hence, JSW Cement is the leading manufacturer of 'green cement' in India. The use of slag in concrete has replaced partially the Ordinary Portland Cement (OPC). As a common practice, blast furnace slag is incorporated in Portland cement production for environmental, technical and economical benefits.
According to Portland blast furnace slag Cement, Portland Pozzolana Cement, and Portland fly-ash Cement (GB1344-1999), the national standard, the content of magnesium oxide in clinker should not exceed 5.0%. If the stability of cement tested by autoclave method is qualified, the content of magnesium oxide can be extended to 6.0%.
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 by-product of an iron blast furnace.

UltraTech Premium is a concrete special cement, produced in UltraTech's state-of-the-art manufacturing facilities with carefully selected premium ingredients to deliver to the customer cement that produces both exceptionally strong as well as exceptionally durable concrete.
Jan 01, 2018· Portland Slag Cement:- PSC is obtained by mixing Portland cement clinker, gypsum and granulated blast furnace slag in suitable proportions and grinding the mixture to get a thorough and intimate mixture between the constituents. The resultant product is cement .
Apr 16, 2017· I had practically used PPC cement in almost all projects. I didn't find any problem. Portland Slag Cement (PSC) Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or blendin...

Ground granulated blast furnace slag (GGBFS) has been used for many years as a supplementary cementitious material in Portland cement concrete, either as a mineral admixture or as a component of blended cement. The use of GGBFS in Portland cement is governed by AASHTO M302. (1) Three types of ground granulated slag cements are typically ...
May 09, 2018· Ground Granulated Blast Furnace Slag concrete. GGBS hardens very slowly so it is generally used along with ordinary Portland cement in concrete. A typical combination is 50% GGBS and 50% ordinary Portland cement. But percentages of 20 to 80 are commonly used. Greater the percentage of GGBS, greater will be the effect of GGBS in concrete.
For a bridge pier and abutment mass concrete project, three mixes were studied: an ordinary portland cement (OPC) mix (Type I PC) and two 70% by weight ground granulated blast furnace slag (GGBFS) mixes (Type II Low Heat PC). One of the slag mixes contained a high range water reducer (HRWR). Tests for compressive strength, freeze-
energy/emissions material, such as blast furnace slag, would have a large impact on reducing those emissions. Using slag cement in concrete can greatly decrease the amount of Portland cement typically used for a specific mixture of concrete. [3] Slag cement can reduce the amount of Portland cement in two ways: direct replacement
Portland Blast Furnace Slag Cement. NCF introduced its Portland Blast Furnace Slag Cement (PSC) as "AlphaCem". It is a Green building material for sustainable construction. AlphaCem is manufactured by uniform inter-grinding of high quality clinker blended with judicious amounts of superior blast furnace slag having high glass content and with ...
The low cost of production of Portland Blast Furnace Slag Cement makes it cheaper than Portland cement. It is for this reason that in recent years, the sales of Portland Blast Furnace Slag Cement have increased. Portland Blast Furnace Slag Cement has a typical light color and an easier 'finish' ability.
Blast Furnace Portland Cement CP III-32; Blast Furnace Portland Cement CP III-40; Early Strength Porland Cement CP V-ARI; Chinese standard GB175-2007. Ordinary Portland Cement P.O 42.5; Ordinary Portland Cement P.O 42.5R; Ordinary Portland Cement P.O 52.5; Ordinary Portland Cement P.O 52.5R; Portland Blastfurnace-slag Cement P.SA 4; Portland ...
Blast furnace slag materials are generally available from slag processors located near iron production centers. Cements containing ground granulated blast furnace slag are available from many producers of Portland cement or directly from ground granulated blast furnace slag cement manufacturers.
Portland Slag Cement – IS 455 Penna 190 MAHA 200 JSW 210 PSC or Portland Slag cement is manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement .
Portland Blast-furnace Slag Cement. A Portland cement mixed with a designated amount of ground granulated blast-furnace slag. The latent hydraulic property of the blast-furnace slag gives excellent long-term strength. Properties Significant chemoresistance, and Suppression of alkali-aggregate reaction (type B and C). Applications
Although blast furnace slag cement has many advantages over ordinary portland cement. The physical properties are similar to OPC. But it has a low heat of hydration and it gives better resistance to chlorides, soils, sulfates and alkalies.

The concrete cubes were photographed, and their sulfate attack ratings and compressive strengths measured at 1, 2, and 5 years. The results showed that concretes made with ground granulated or pelletized blast furnace slag and portland cement generally had good sulfate-resisting properties when the slag content was 70 percent and above.
Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.
