Jul 30, 2020· 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
Concrete produced with our slag cement CEMSlag TM often yields higher 28-day compressive and flexural strength than comparable products. Reduced heat hydration Concrete produced with CEMSlag TM has lower heat of hydration that reduces thermal cracking, especially important for projects that involve mass concrete structures like dams.
Slag cement is used in nearly all types of concrete construction: pavements, structures and foundations, mass concrete (i.e., dams and retaining walls) and precast concrete products such as pipe and block. Advocates point to a number of ways in which slag cement makes concrete better and more consistent: • Easier to place and finish
An interesting paper by Bakharev et al. (2000) tried to rationalize the study of workability of concrete that incorporated alkali-activated slag as the only binder. The activators were liquid sodium silicates (4 ± 7% Na, mass of slag) and a multicompound activator (NaOH + Na 2 CO 3) (8% Na, mass of slag).To ameliorate the workability, measured by the slump loss test, different additives have
Apr 08, 2020· Concrete made with recycled steel slag is 17 percent stronger than traditional concrete. Disposing of slag is a millennia-old problem,but the "waste material" is highly sought in construction.
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.

The NewCem® Slag Cement Advantage. To produce quality slag, a producer needs to have slag with an ideal chemistry from a consistent source and needs to have equipment close to the slag source to provide rapid quenching of the slag. Lafarge engineers and scientists have led North America in the research and development of specifications for slag.

Ground granulated blast-furnace slag (GGBFS), sometimes simply referred to as “slag”, is a glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water. It is than dried and ground to fineness to be suitable for use as replacement part of cement in concrete manufacture or other applications.
Dec 21, 2005· Mike Pistilli of Prairie Materials, Chicago, helped draft this column. Mike has been in the portland cement, fly ash, slag, chemical admixture, and concrete industries for decades, and well recognizes the price of concrete and concrete-making material and its impact on concrete and construction practices. We thank him for his valuable assistance.
difference in the level of deicer scaling that occurred in slag cement concrete versus OPC concrete (Dubovoy, et al, 1986). Afrani and Rogers (1994), on the other hand, recorded much greater scaling loss for concrete with high slag cement replacement compared to 100% OPC concrete. Also noted was a difference in deicer scaling resistance apparently
Slag concrete generally develops strength slowly than concrete without GGBFS. Although this situation is a disadvantage for early ages of concrete such as 3 or 7 days, slow development of strength is an advantage for ages 28 days or later. Because concrete containing GGBFS continues to gain strength at a higher rate at later ages than OPC concrete.
In the production of ready mixed concrete, GGBS replaces a substantial portion of the normal Portland cement concrete, generally about 50 %, but sometimes up to 70%. The higher the portion, the better is the durability. The disadvantage of the higher replacement level is that early age strength development is somewhat slower.
Concrete consists of a mix of ingredients, including Portland cement, pozzolans, water, coarse aggregates, fine aggregates, and additives. Concrete may also contain mineral colors, granulated blast-furnace slag, and blended cements. When fresh, cement can be molded hours after it is produced.

Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the

The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. Sign Up VIP members get additional benefits.
Chemically, slag is a mixture of lime, silica and alumina, that is, the same oxides that make up Portland cement. Cementitious properties are generated when ground granulated slag reacts with water. Using slag cement to replace a portion of Portland cement in a concrete mixture is an efficient way to make concrete more consistent.
