Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or mixing the Ground Granulated Blast Furnace Slag (GGBS) with Ordinary Portland Cement by means of mechanical blenders. It is created with a blend of 45- 50% slag, 45% & 50% clinker, and 3-5% gypsum.
Slag Cement, formerly referred to as ground, granulated blast-furnace slag, is a glassy, granular material formed when molten, iron blast-furnace slag is rapidly chilled - typically by water sprays or immersion in water - and subsequently ground to cement fineness. Slag cement is hydraulic and can be added to cement as an SCM.
Sep 30, 2019· The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete .
Concrete made with slag cement provides higher compressive and flexural strengths compared with portland cement concrete. SCIC #14, Compressive and Flexural Strength, examines the factors that effect concrete strength, and explains how slag cement improves both compressive and flexural strength of concrete.
Slag cement lowers the heat of hydration of a concrete mixture, which reduces the risk of early age thermal cracking, a major benefit for large or mass concrete placements. It lowers the total alkalis of a concrete mixture thus reducing the risk of alkali-silica reactions. Equally important, slag cement delivers improved workability.
PSC or Portland Slag cement is a kind of blended cement 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. The Portland Po...
The same standards of care should be applied when handling all types of concrete, including concrete made with slag cement. SCIC #5, Producing and Placing Slag Cement Concrete, provides an overview of methods for handling slag cement concrete. Slag cement is stored, batched and transported in a similar manner to that of portland cement.
Slag cement has also been used effectively in the design of self-consolidating concrete mixtures. Proportioning Precast/Prestressed Concrete Mixtures with Slag Cement. Precast/prestressed manufacturers who have successfully incorporated slag cement in their products have used slag cement in ranges from 20 to 50 percent of cementitious material.
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

how is slag cement manufactured - ellul. how slag cement is manufactured - parhamschool. Portland slag Cement (IS: 455) It is manufactured either by intimately intergrinding a mixture of Portland cement clinker and granulated slag with addition of gypsum or calcium sulphate, or by an intimate and uniform blending of Portland cement and finely ground granulated slag.
PDF | This paper aims to study experimentally, the effect of partial replacement of coarse and fine aggregates by steel slag (SS), on the various strength and durability properties of concrete, by ...
What Is Slag Cement Where does it come from How it is made How does it react Terminology Specifications For Slag Cement ASTM C989 & AASTHO M 302 ASTM C595 & AASHTO M 240 DOT specifications Slag Cement's Effect On Concrete Typical replacement values Effects on compressive strength Reducing permeability Sulfate attack Mitigation
Portland Slag Cement (PSC) Portland Slag cement is manufactured by either inter- grinding the Portland cement clinker, Gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement by means of mechanical blenders.
Slag cement does not contain carbon and maintains a consistent particle size, thus ensuring a stable air void system. Concrete pipe manufacturers can depend on slag cement to help reduce the variability of their concrete materials. Proportioning Concrete Pipe Mixtures with Slag Cement. Concrete pipe manufacturers who have successfully ...
Sep 30, 2019· 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: - Blast-furnace slag—The 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 .
(1) Three types of ground granulated slag cements are typically manufactured. They include Portland cement as covered by AASHTO M85 (2), Portland blast furnace slag cement (blended cement type IS), and slag cement (slag cement type S) as per AASHTO M240. (3)
Ground granulated blast furnace slag cement carries off-white color while this color is also observed in concrete that is made with GGBFS. The GGBFS concrete leads to gain strength gradually as compare to concrete made with Portland cement. Thus concrete encompassing GGBFS is quite less permeable and more stable chemically in comparison to ...
May 11, 2017· Slag is a by product of steel production. It is added to concrete to replace cement in concrete. Concrete with slag is easier to work and less susceptible to freeze thaw cycles. There are other benefits as well. Concrete with slag is being used in road construction in some states.
Slag cement is commonly found in ready-mixed 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.
Ground granulated slag is often used in concrete in combination with Portland cement as part of a blended cement. Ground granulated slag reacts with a calcium byproduct created during the reaction of Portland cement to produce cementitious properties. Concrete containing ground granulated slag develops strength over a longer period, leading to ...
Portland blast-furnace slag cement, or Blast furnace cement (ASTM C595 and EN 197-1 nomenclature respectively), contains up to 95% ground granulated blast furnace slag, with the rest Portland clinker and a little gypsum. All compositions produce high ultimate strength, but as slag content is increased, early strength is reduced, while sulfate ...
Nov 19, 2008· The two byproducts differ in availability and characteristics. Slag, which is left over in blast furnaces when steel is made, can make up more of the concrete .
