As a byproduct of existing industrial processes, GGBS is even more sustainable than many other cement substitutes such as fly ash. Our products conform to BS EN 151671. This is the British standard for the use of Ground Granulated Blast furnace Slag in concrete, mortar and grout. GGBS counts fully towards the cement content of concrete mixes.
Ground granulated blast furnace slag (GGBFS) shall comply with Specifiion 3102 and AASHTO M 302. Blended cements shall comply with Specifiion 3103 and AASHTO M 240. Acceptance is judged on the basis of time of set, false set, fineness, soundness, air content of the mortar, chemical analysis, and compressive strength. The slag activity
Granulated slag obtained from blast furnace slag is wet and coarse in nature and can not be useful directly. So drying and grinding process are carried out to make it useful. Normally ball mill is used to make it fine in nature. There is no any chemically changes happens during this process only physical nature of the material is being changed ...
national slag association Since 1918, The NSA has promoted the use of Blast Furnace and Steel Furnace Slag. Blast Furnace slag has been called the "AllPurpose Aggregate" as it can be used in all construction appliions as either a normal weight or lightweight (expanded or pelletized) aggregate depending on how it was formed and processed.

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.
Ground granulated blastfurnace slag (GGBFS), sometimes simply referred to as "slag", is a glassy granular material formed when molten blastfurnace slag is rapidly chilled, as by immersion in water. It is a nonmetallic product, consisting of silies and aluminosilies of calcium and other bases, developed in a molten condition simultaneously with iron in a blast furnace. It is used ...
The effects of ground granulated blast furnace slag were studied on RCCP durability. The durability properties such as water absorption, permeability and freezethaw cycles were considered. The moisture content required for the concrete to reach its
The effect of replacing 20–70 % of ordinary Portland cement (OPC) by ground granulated blast furnace slag (GGBS) on the mechanical properties, weight loss and carbon footprint of oil palm shell ...

The promotion of blast furnaces slag in construction industry aims at protecting the environment, fighting against the nuisance such as waste dumps and promoting local products. The use of granulated slag as a part replacement of Portland cement or in the production of clinker free binder constitutes a valuable outlet for this product. The aim of this study is the characterization of local ...
Ground Granulated Blast Furnace Slag (GGBS) Jul 12, 2021· Ground granulated blast furnace slag (GGBS) is a byproduct from the blastfurnaces used to make iron. furnaces are fed with a controlled mixture of ironore, coke and limestone, and operated at a temperature of about 1,500° granulated slag is further processed by drying and then grinding in a vertical roller mill of rotating ...
Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. In this article we discuss about the manufacture, constituents, properties ...
