Why is there a Slag Cement Association?
Why is there a Slag Cement Association?
The Slag Cement Association represents companies that produce and ship slag cement (ground granulated blast furnace slag) though the USA. The Slag Cement Association serves as the leading source of knowledge for slag cement and slag blended cements through promotion, education, and technology development.
What is the 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. Once the slag has been cooled and ground to a usable fineness it is stored and shipped to suppliers throughout the United States.
Is slag cement good for construction?
Portland Slag Cement, commonly known as PSC, is blended cement. PSC has been voted as the most suitable cement for mass construction because of its low heat of hydration.
What is the benefit of slag cement?
Slag concretes have improved long-term strengths even though their early strength development is lower than portland cement concretes. They also have lower permeability and improved durability. Slag cement generally costs less than portland cement.
What is slag cement disadvantages?
Disadvantages of Blast-Furnace Slag Cement Early Strength is low; therefore, it cannot be used in Reinforced Cement Concrete (RCC) works. As the initial setting time is high, this cement is not used for emergency or repair works.
What is the difference between portland cement and slag cement?
When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement paste (pozzolanic reaction), resulting in a more refined microstructure than that of a plain portland cement.
Where is slag cement used?
Slag cement is used in virtually all concrete applications: Concrete pavements. Structures and foundations. Mass concrete applications, such as dams or retaining walls (SCIC #9, “Reducing Thermal Stress in Mass Concrete”)
What is premium 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.

What are the uses of slag cement?
Used in ready mix concrete plants.
What is slag concrete?
Slag Concrete. a lightweight concrete, in which the aggregate consists of metallurgical or furnace slag that has been crushed, dispersed, and purified of contaminants. It is used in the erection of cast-in-place wall structures (mainly building walls, ceilings, and floors) and in the prefabricated manufacture of concrete, stone, blocks, and panels.
What are the effects of slag powder in mortar?
The slurry structure of slag powder mortar is relatively dense and slag powder can absorb the calcium hydroxide crystals generated by cement hydration, improving the interface structure of mortar, so the resistance to penetration and frost of slag powder mortar is significantly better than that of ordinary mortar. Since slag powder has a stronger effect of adsorbing chloride ions, it can effectively prevent chloride ions diffusing into it, improving the resistance to chloride ions.
How does slag forms?
Slag, by-product formed in smelting, welding, and other metallurgical and combustion processes from impurities in the metals or ores being treated. Slag consists mostly of mixed oxides of elements such as silicon, sulfur, phosphorus, and aluminum; ash; and products formed in their reactions with furnace linings and fluxing substances such as limestone.
