GGBS is an acronym for Ground Granulated Blast Furnace Slag, a by-product from the manufacture of Iron. Ecocem GGBS is used in combination with Portland cement to produce superior longer lasting concrete. A replacement rate of up to 70% is permitted by I.S EN 206-1..
Likewise, people ask, what is the use of Ggbs in concrete?
GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight.
Beside above, is Ggbs cheaper than cement? As GGBS cement is slightly less expensive than Portland cement, concrete made with GGBS cement will be similarly priced to that made with ordinary Portland cement.
Also question is, what is Ggbs material?
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. The iron ore is reduced to iron and the remaining materials form a slag that floats on top of the iron.
Is Ggbs a admixture?
Admixtures are added in concrete to improve the quality of concrete. Mineral admixtures include fly ash (FA), silica fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA) which possess certain characteristics through which they influence the properties of concrete differently.

What does Ggbs stand for?
GGBS is an acronym for Ground Granulated Blast Furnace Slag, a by-product from the manufacture of Iron.Why Silica is used in cement?
Silica (SiO2) Sufficient quantity of silica helps for the formation of di-calcium and tri-calcium silicates which imparts strength to the cement. Excess silica in cement will increase the strength of cement but at the same time setting time of cement also increased.What is difference between OPC cement and PPC cement?
Difference Between OPC Cement and PPC Cement. Portland Pozzolana Cement is a variation of Ordinary Portland Cement. Pozzolana materials namely fly ash, volcanic ash, are added to the OPC so that it becomes PPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing.What is slag used for?
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 the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.Why is slag used in cement?
Slag cement is most widely used in concrete, either as a separate cementitious component or as part of a blended cement. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion.What is the difference between fly ash and Ggbs?
The reaction heat per unit mass of GGBS is only 16·7% higher than that of fly ash. The main reason for the difference of hydration heats between GGBS binder and fly ash binder is that GGBS shows much higher hydraulic activity than fly ash.What is PFA concrete?
Pulverised Fuel Ash (PFA), aka 'Fly ash' as a cement substitute. PFA is a by-product of coal-burning power stations. PFA is always used in conjunction with Portland Cement. It is employed in ratios ranging from 80% Pc and 20% PFA – 60% Pc and 40% PFA according to the ultimate function of the cement.Does fly ash make concrete stronger?
The same qualities that cause fly ash to absorb moisture more easily than cement also make fly ash stronger. Concrete created with fly ash tends to be more stable and exhibit a higher grade of overall strength than concrete made with traditional cement products.Is Ggbs a code?
As per IS 455 portland slag cement specification and as per ammendment no 4 of May 2000. So according to IS code you can replace portland cement up to 70% by using GGBS. You may try replacing cement by more than 70% and share your experiance. The specifications are for manufacturing of cement.How is Metakaolin produced?
Metakaolin is a pozzolan, probably the most effective pozzolanic material for use in concrete. It is a product that is manufactured for use rather than a by-product and is formed when china clay, the mineral kaolin, is heated to a temperature between 600 and 800ºC.What is a good substitute for concrete?
Gravel is one of the more common alternatives to concrete. There are a few different types you can find in the home improvement store that can replace concrete cement used for driveways and walkways. These include pea gravel, crushed stone, and quarry process.How is cement made?
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.How does a blast furnace work?
The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The hot air that was blown into the bottom of the furnace ascends to the top in 6 to 8 seconds after going through numerous chemical reactions.Is Ggbs a pozzolan?
A GGBS is NOT a pozzolan. The free vitreous silica, or silica aluminates like in the Pozzolanic ashes, is unwanted because it can contaminate the steel and render it useless. Nevertheless the combination of calcium / aluminum / silica / iron compounds is less reactive than in cement. The setting of GGBS is “very” slow.What is the specific gravity of Ggbs?
2.2. It is a granular product with very limited crystal formation, is highly cementitious in nature and, ground to cement fineness, and hydrates like port land cement. The specific gravity of GGBS is 2.85.How is blast furnace slag produced?
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. This forces the chemical reaction to take place throughout the ore, not only at the surface.Where does clinker come from?
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.What is eco friendly concrete?
What Is Eco-Friendly Concrete ? Concrete that uses less energy in its production & produces less carbon dioxide than normal concrete is referred to as Eco-friendly or Green Concrete. Set-Back of Traditional Concrete ? Traditional concrete is made from a mixture of cement, sand, gravel and water.What is slag used for in a blast furnace?
Pelletized blast furnace slag has been used as lightweight aggregate and for cement manufacture. Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material. and granulated slag have also been used as sand blasting shot materials.
