Ground granulated blast-furnace slag
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in calcium silicate hydrates (CSH) which is
Ground Granulated Blast Furnace Slag an overview
Slag. Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the
Effect of Ground Granulated Blast Furnace Slag
Nov 24, 2021 This study was conducted to investigate the effect of ground granulated blast furnace slag on the structural performance of precast concrete beams, evaluating the flexural, shear and bonding performance by using the replacement ratio of the ground granulated blast furnace slag as a variable. The design strength of the concrete was set at 45 MPa in

GGBS Concrete CSMA The Cementitious Slag Makers
Ground granulated blast-furnace slag is off-white in colour and substantially lighter than Portland cement CEM I. This whiter colour is also seen in concrete made with GGBS, especially at CEM I replacement levels of 50% and above. The more aesthetically pleasing appearance of GGBS concrete can help soften the visual impact of large structures
Slag
Today, ground granulated blast furnace slags (GGBFS) are used in combination with Portland cement (PC) to create "slag cement". GGBFS react with portlandite (Ca(OH) 2 ),which is formed during cement hydration, via the pozzolanic reaction to produce cementitious properties that primarily contribute to the later strength gain of concrete.

Fly Ash, Slag, Silica Fume, and Natural Pozzolans,
SLAG Ground granulated blast-furnace slag (Fig. 3-5), also called slag cement, is made from iron blast-furnace slag; it is a nonmetallic hydraulic cement consisting essentially of sili-cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. The molten slag at a temperature of about 1500°C
What is 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. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield
Concrete Designing Buildings
Waste materials can be included within the concrete mix such as Recycled Crushed Aggregate (RCA), Ground Granulated Blast-Furnace Slag (GGBS) and Pulverised Fuel Ash (PFA). In addition, moves are being made to assess the potential of using recycled concrete,however, issues such as moisture content and material variability may make this unviable.
What is GGBS? CSMA The Cementitious Slag Makers
GGBS (Ground Granulated Blast-furnace Slag) is a cementitious material whose main use is in concrete and is a by-product from the blast-furnaces used to make iron. Blast-furnaces operate at temperatures of about 1,500°C and are fed with a carefully controlled mixture of

How lead is made material, used, processing, product
A blast of air comes through the lower part of the furnace, combusting the coke. The burning coke generates a temperature of about 2,200°F (1,200°C) and produces carbon monoxide. The carbon monoxide reacts with the lead and other metal oxides, producing molten lead, nonmetallic waste slag, and carbon dioxide.
Floating Slab Construction Applications and Advantages
Here the need for ground preparation is reduced to a larger extent. The floating slabs are called as monolithic slabs as they have no connection with the foundation. If it's the case, only after curing of the foundation we cast the floating slab. Ground Granulated Blast Furnace Slag in Concrete & its Advantages. Neenu S K EDITOR. Related Posts.
