Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. It is a byproduct of the ironmaking industry. For every tonne of GGBS used in a concrete mix, the embodied CO 2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement. What is GGBFS? The abbreviation ...
Slag Cement is recycling of blast furnace slag has been used for a long time in the cement industry. It is often used in composite cement. Slag is not hydraulic by it self, but if an activator (e. g. lime) is present, it takes part of the hydration reactions and makes a substantial contribution to the hydration product. Blast furnace slag can also be used as a raw material for the manufacture ...

The xcoordinate indies which product throughputs can be generated using the respective mills. The width of the fields is a measurement of the output factor. The dimensions H and A in turn describe the height of mills with classifier, the footprint diameters and ...
Ground Granulated BlastFurnace Slag. Slag is a byproduct from steel plants, which is obtained from blast furnaces, during the separation of iron from iron ore. The process involves cooling of the slag through highpressure water jets, this leads to formation of granular particles. The granulated slag is further processed by drying and then ...
Test results of a comprehensive program to investigate the temperature and humidity environment effects of deformations of concrete and mortar made with blastfurnace slag cement (BFSC) or ordinary portland cement (OPC) are presented. The program was composed of creep, shrinkage, and thermal expansion coefficient tests. Creep tests were performed in the fog room (called basic creep), drying ...

Strength Development Chart for Various Types of Cement. The Multifold Advantages of PSC. PSC's inherent chemistry gives it several advantages over ordinary cement. Apart from being more environment ...
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 2008 – 2012 emissions of greenhouse gases by 6% from 1990 levels.
Enhanced Model and Simulation of Hydration Process of Blast Furnace Slag in Blended Cement Yao Luan1, Tetsuya Ishida2, Toyoharu Nawa 3 and Takahiro Sagawa4 Received 1 April 2011, accepted 4 October 2011 doi:/ Abstract A hydration model for cementitious materials was applied to slag blended cement. The original model was found to overestimate the hydration degree of slag, .
Ground Granulated Blast Furnace Slag (GGBFS), otherwise known as slag, is a byproduct of the steel and iron industry which is milled to a fine consistency. Slagment is the registered trade name of our Ground Granulated Blast Furnace Slag (GGBFS). It is a latent hydraulic binder that is used in concrete and other construction appliions as a partial cement replacement material. We have the ...
Grinding of cement and/or granulated blastfurnace slag – Material separation in the filter. The cement components are ground, dried, and classified in the Pfeiffer vertical roller mill. Moist feed materials can be fed to the mill separately from warm and dry feed materials. Product quality and product fineness can be adjusted within a wide ...

Slag cement, originally known as granulated blastfurnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is converted to a cementlike material by rapidly ...
Cement is an essential constituent for the production of concrete. Nowadays, the supplementary use of cement such as industrial byproduct and agricultural waste material has become an integral part of concrete construction due to their cost effective and sustainable environmental benefits. The industrial (metallurgical) by productGranulated Blast Furnace Slag (GBFS) contains a non ...
· Ground granulated blast furnace slag (GGBS) is a nonmetallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silies and aluminates of calcium and other bases. The size of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 /kg.
