Pelletization is a worldwide process used in producing artificial aggregates although its usage is not common in Turkey. In this study, lightweight aggregates (LWAs) were manufactured through cold-bonding pelletization of ground granulated blast furnace slag (G) and two types of fly ash with different finenesses (Fly ash A and B). Ordinary …

Blast Oxygen Furnace (BOF) slag represents one of the largest waste fractions from steelmaking. Therefore, slag valorisation technologies are of high importance regarding the use of slag as a secondary resource, both in the steel sector and in other sectors, such as the construction or cement industries. The main issue regarding the …
With this background, this study has been planned. 2. EXPERIMENTAL METHOD Slag aggregate sample was collected from a crushing plant of induction furnace slag of a local steel manufacturing company. The slag and brick aggregates were tested for grading, unit weight, abrasion, specific gravity, absorption capacity and abrasion as per ASTM …

Aggregate crushing plant produce construction aggregates widely used for making concrete production. The aggregate process consists by progressive stages of crushing, screening, and washing. ... slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined material in the world. Aggregates are a component of …
Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction (Sheen et al., 2013; Manso et al., 2004).
The coarse aggregate used in this study of size between 10 mm–12.5 mm. IF steel slag as coarse aggregate was replaced in various proportions (0%, 25% and 50%) instead of natural coarse aggregate in concrete.

Blast Furnace Slag is produced to meet state specifications for gradation and other key requirements. The American Society of Testing and Materials (ASTM C-125, Definition of Terms Relating to concrete and concrete Materials) defines Blast Furnace Slag as "the non-metallic product consisting essentially of silicates and aluminosilicates of calcium …
Slag, crushed 1/4 inch weigh(s) 1.185 gram per (cubic centimeter) or 0.685 ounce per (cubic inch). See this and other substances density in 285 measurement units
Blast furnace slag aggregate comes in two forms: Air cooled blast furnace slag, results when molten slag from a blast furnace slag cools slowly by ambient air (as opposed to rapid quenching), and is processed through a screening and crushing plant for use principally as a construction aggregate. Air cooled slag is not cementitious.
This article reviews the use and effectiveness of ground granulated blast furnace slag (GGBS) as an alternative to cement in concrete. It discusses the manufacturing, properties, performance and …
The present study evaluates the effect of utilising granulated blast furnace slag as a partial substitution of the fine fraction of natural aggregates on various concrete parameters using the general factorial approach. Two levels of the water/cement ratio (0.45 and 0.5) and four different percentages of granulated blast furnace slag (0, 20%, 40% …
About 20% of slag is dumped into the slag cooling pit and crushed with mechanical crushing systems after cooling. The crushed slag is passed through magnetic separators to separate the metal. The metals are collected as recycled metal and the remaining slag is an iron free material suitable for cement plant admixture with …
Commonly used aggregates include sand, crushed or broken stone, gravel (pebbles), broken blast-furnace slag, boiler ashes (clinkers), burned shale, and burned clay. Crushed aggregate in its...
