ing steels, the slag is generated at 3 different stages of process-ing and accordingly classified as: blast-furnace slag, electric arc furnace slag and ladle slag [10]. The electric arc furnace slag (EAFS) has a chemical composition more close to that of the cement clinker compared to the ground granulated blast-furnace slag (GGBFS).

The main by-products of the steel industry, blast furnace (BF) slag and steel-making (SM) slag, can partially replace cement in concrete because of its potential hydraulicity [1,2,4,5,6,7,8,9].According to previous studies, about 70% of the total production of BF slag has been used as a replacement for Portland cement due to its numerous advantages, e.g., an increase in long-term strength and ...

Iron making slag granulation technology has been in regular use for converting it into glassy granules for use in portland slag cement making along with clinker. Recently, ground granulated slag (GGBFS) is also developed using the granulated slag for use as a replacement of ordinary portland cement by ready mix concrete (RMC) manufacturers.

cement production or (partial) substitution of cement in concrete production reduces these CO2 emissions, especially if material is used which is seen as a waste of other processes, such as Fly Ash (FA) from coal power plants and Granulated Blast Furnace Slag (GBFS) from the iron and steel sector.

GGBS concrete is characterized by high strength, lower heat of hydration,

This paper examines the possibility of using ground-granulated blast-furnace slag (GGBFS) as a partial replacement of filler in polymer grout. In this study, river sand was replaced by GGBFS at levels of 0 (control), 10, 20, and 30% by weight.

Granulated blast furnace slag (GBS) is the most important steel industry by-product. The production is almost 0.23 tons of slag for each ton of cast iron and 0.1 ÷ 0.2 tons for each ton of steel . According to EUROSLAG data, the production of granulated blast furnace slag was 23 million tons in 2012. The huge amount of EAF granulated slag ...

granulated slag specifications were based on that of ground granulated blast furnace slag (GGBFS) specifications (EN-197)8 which is widely used in the cement industry. Table 2 contains the GGBFS target specifications and the corresponding modified slag results. A mineralogical analysis was conducted to determine the presence of
