Accordingly, the present invention provides an improved process for the production of Portland slag cement using granulated blast furnace slag, which comprises: (viii) forming of cement clinker by known process, (ix) ballmilling of cement clinker for a period ranging between 3060 minutes in dry condition, (x) reducing size of granulated blast furnace slag by any process to obtain the size in ...
Portland BlastFurnace Slag Cement a cement produced by grinding portland cement clinker together with pellets of blastfurnace slag (30–60 percent of the total weight) and a small amount of gypsum. It differs from ordinary portland cement by a slower increase in strength in the initial hardening period and an increased water resistance. It is used ...
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
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.

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 intergrinding in the Portland cement clinker, Gypsum Granulated Slag or blendin...
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.
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 ...
Portland blastfurnace slag cement definition is a cement produced by intimately intergrinding a mixture of portland cement clinker and granulated blastfurnace slag in widely varying proportions.
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
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 sulfateresisting properties when the slag content was 70 percent and above.
Blastfurnace slag is used in makingfour 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
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 intergrinding of high quality clinker blended with judicious amounts of superior blast furnace slag having high glass content and with ...
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 .
Slag Cement, has been incorporated into concrete projects for over a century to improve durability and reduce life cycle its measurable benefits in concrete are better workability and finish ability, higher compressive aggressive chemicals. Tiger Portland Blast Furnace Slag Cement is special blended cement with low heat of hydration characteristics for mass concreting.
Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.
Portland BlastFurnace Slag Cement UltraTech Premium. UltraTech Premium is a concrete special cement, produced in UltraTech''s stateoftheart manufacturing facilities with carefully selected premium ingredients to deliver to the customer cement that produces both exceptionally strong as well as exceptionally durable concrete.
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.
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.

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.
Portland Blastfurnace Slag Cement. A Portland cement mixed with a designated amount of ground granulated blastfurnace slag. The latent hydraulic property of the blastfurnace slag gives excellent longterm strength. Properties Significant chemoresistance, and Suppression of alkaliaggregate reaction (type B and C). Applications
PORTLAND SLAG CEMENT Portland Slag Cement is manufactured by us as per IS: 455 by intergrinding not less than 35% of ordinary Portland cement clinker and granulated blast furnace slag. It has the advantages in generating heat less quickly than OPC. Because of its high sulphate resistance, it is used in sea water
