Product Details GGBFS is obtained by quenching molten iron blast furnace slag (a by-product of iron and steel making) in water or stream, to produce a glassy granular product that is then dried and ground into a fine powder. Slag powder as a new type of high performance concrete admixture,has advantages of improving the performance of concrete.
Jul 07, 2015· Therefore, slag from SD-2 was ground in a laboratory ball mill into a powder with a specific surface of 4000 to 4500 cm2/g which was used as a cementitious material and a fine-dispersed aggregate for the fine-grained slag concrete.
Aug 28, 2020· 10%· Based on the fundamental principles of preparing reactive powder concrete (RPC), a new type of RPC was composed by replacing cement with the active powder component ultra-fine ground granulated blast-furnace slag (GGBS). GGBS is proposed as a potential alternative to silica fume (SF), which is currently the most commonly used RPC mineral admixture. In …
Oct 02, 2021· Water slag has important use in cement industry, which can be used as cement mixture. It can also be used as concrete modifier to improve the performance of concrete. Using blast furnace slag superfine powder as cement additive can not only solve the problem of blast furnace slag outlet, but also provide a cheap raw... Read More Read More
Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water, dried and ground to a fine powder. The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely.
Finely ground glass powder (particle size of less than 38 μm) can be used as a pozzolan material in concrete because of its high reactive silica content. This paper studied the properties of ...
2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement (ACI Committee 233, 2004). The term slag cement will be used throughout this paper when referring to finely-ground granulated blast-furnace slag.
Apr 23, 2017· This cement, called Eisen Portland cement in Germany, is made of a finely-ground mixture of Portland cement and granulated slag, usually in the proportion of about 3 of cement to 1 of slag. As before mentioned, this class of cement probably was at first only a fraudulently adulterated Portland cement, but it is now extensively made and sold as ...
Jan 19, 2021· The slag powder is the water slag produced in the process of blast furnace iron smelting, and the powder formed after processing by the slag mill. The same point is that it needs to be pulverized by a mill to prepare a powder, and then make it a high value-added product, increasing the economic benefits of the enterprise.
A method is provided for manufacturing cement from a raw material mixture which includes finely ground steel slag. Selected quantities of steel slag and other raw materials are mixed with each other and supplied to a raw mill. The steel slag and other raw materials are preferably ground to a fine, dry powder. For some applications, the dry powder is preferably supplied to a blend tank for ...
Jan 30, 2018· The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity …
May 09, 2018· This slag is periodically tapped off as a molten liquid and then rapidly quenched with large volumes of water. This process optimizes the cementitious properties and produces granules like coarse sand. This granulated slag is then dried and ground to a fine powder. It is also knows as slag cement because it has similar properties as cement clinker.
The method of introducing of finely ground granulated blast furnace slag (GBFS) in the composition of the cement as a result of dry mixing of the material with the additive is considered. The aim of the research was to study the effect of the addition of finely ground slag on the construction, technical, physical, mechanical, and structural characteristics of cement with mineral additives.

Mar 20, 2021· The mechanical properties and hydration mechanism of ultrafine ground granulated blast furnace slag powder (UFS)-cement-steel slag powder (SS) ternary cementitious material systems were studied. The chemical effects and contribution ratios of UFS and SS in ternary system at different hydration ages were also investigated.
TB. TB-0102 — Ground Granulated Blast-Furnace Slag Its Chemistry and Use with Chemical Admixtures Technical Bulletin a typical Class C fly ash and a typical Class F fly ash You will note that the GGBFS and the two fly ashes have the same kinds of oxides as the cement GGBFS must be finely ground before it can be used in concrete
1 · Recently, interest in environmentally friendly development has increased worldwide, especially in the construction industry. In this study, blast furnace slag powder (BFSP) and mixed steel fine aggregates were applied to cement mortars to reduce the environmental damage caused by the extraction of natural aggregate and to increase the recycling rate of steel by-products in the …
Ground-granulated blast- furnace slag (GGBS): Ground-granulated blast furnace slag is a by-product from the blast furnaces used in the iron manufacturing industry. GGBS is obtained by quenching molten iron slag (a by-product of iron and steel making) in water or steam, to produce granular product i.e. then dried and ground into a fine powder.
