Blast Furnace Slag in Cement and Concrete 1 10 As there are many types of slag it should be noted that the term slag used throughout this publication refers specifically to metallurgical slag produced in modern blast furnaces blast furnace slag and not basic oxygen steel slag or electric arc furnace slag which are generally referred to as steel furnace slags Although
Ground granulated blast furnace slag cement GGBS a byproduct in steel manufacture has been used to improve concrete strength development during accelerated curing but poses a challenge of increased shrinkage In this paper two types of granulated blast furnace slag cements were used to study mechanical and shrinkage properties of water cured and concrete subjected to accelerated curing
Key words high alumina cement blast furnace slag gehlenite hydrate hydration conversion 1† Introduction High alumina cement provides high strength compared with ordinary portland cement in the early period of hydration but the high strength is lost associated with conversion reaction of calcium aluminate hydrates as time goes by There have been many investigations …
Expanding the use of Portland blast furnace slag cement is one measure included in the plan to achieve the targets of the Kyoto Protocol and there are large expectations for its ability to help reduce CO 2 emissions Under the Kyoto Protocol Japan has made a commitment to the world to reduce its 2021 2021 emissions of greenhouse gases by 6% from 1990 levels
Making cement is energy intensive generating up to 176 kg CO 2 for each tonne of concrete manufactured Because Ground granulated blast furnace slag GGBS or GGBFS is a lower carbon building material it s considerably more environmentally friendly The reduction of in greenhouse gas emission can be as high as 45% depending on the mix and application …
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
LIBERTY Galați has for the first time exported 50 000 tonnes of blast furnace slag so that it can be converted into very low carbon cement at a specialist factory in France
Slag cement or GGBFS is granulated blast furnace slag that has been finely ground and that is hydraulic cement When slag cement is mixed with water however the initial hydration is much slower than portland cement mixed with water; therefore portland cement or salts of alkali metals principally sodium and potassium or lime are used to increase the reaction rate of slag cement ACI 233R
Making cement is energy intensive generating up to 176 kg CO 2 for each tonne of concrete manufactured Because Ground granulated blast furnace slag GGBS or GGBFS is a lower carbon building material it s considerably more environmentally friendly The reduction of in greenhouse gas emission can be as high as 45% depending on the mix and application GGBFS has less embodied …
Concrete properties can be improved using Fine Blast Furnace Slag BFS The latter was used to replace cement in concrete at 10% 15% 20% 25% and 30% proportions and properties of both fresh and hardened concrete improved Best workability evaluated by slump and Table tests was recorded at 30% of BFS addition VEBE time an indication of workability of …

A Guide to the Use of Iron Blast Furnace Slag ii Cement and Concrete 1 a INTRODUCT Throughout the world there is an increasing focus on the need to recycle and to more fully utilise by products of manufacturing processes in an attempt to conserve our finite natural resources Technical evaluation supported by field experience has shown that a by product such as iron blast furnace slag has in
JSW Portland Slag Cement PSC is a blended cement where in some portion of OPC is replaced with Ground granulated blast furnace slag GGBS to make the structures long lasting & durable Strength Development Chart for Various Types of Cement The Multi fold Advantages of PSC PSC s inherent chemistry gives it several advantages over
Blast Furnace Cement Blast Furnace Cement is the mixture of Ordinary Portland Cement and fine granulated blast furnace slag is obtained in steel plant as the by product of steel making is produced during the seperation of the molten steel from impurities in steel making furnaces About 70% of slag is used in the…
The efficiency which the molten blast furnace slag is rapidly chilled as well as the chemical composition of the slag source largely determines its cementitious properties for use in concrete After the granulated blast furnace slag is formed it must be dewatered dried and ground using processes similar to those used with Portland cement clinker to make Portland cement
Blast Furnace slag can be used as a high value Partial replacement to conventional Portland cement Most of the modern steel plants now completely granulate the BF slag and use in cement making However this granulated BF slag GBS is very similar to natural sand and can be used directly as fine aggregate in construction works
