These findings notwithstanding, the distances from the aggregate quarry to the asphalt plant, as well as the distances involved in BOF slag production, differ depending on particular conditions. Therefore, a more interesting comparison would be to consider the carbon footprint of different transport distances for each aggregate.
The 3m tons integrated steel plant produces both blast furnace slag and steel slag. The blast furnace slag after granulation, is consumed by the neighbouring Indorama Cement Ltd, in the manufacture of Portland Slag cement and GGBFS conforming to BS-6699. The steel slag after crushing is partly recycled through a sintering plant.
2.1.1 Basic Oxygen Furnace Slag Basic oxygen furnace (BOF) slag arises when steel is produced from pig iron, direct reduced iron or scrap. The amount of slag depends on the amount of silicon in the pig iron, because this is connected with the amount of lime added. The BOF is used to produce steel. The objective in oxygen steelmaking is to

Blast furnace slag has great potential for use as an alternative coarse aggregate to replace conventional/natural coarse aggregates in constructing road subbase and bituminous surfacing layers [7].
It can be categorized by either the process in which it was generated (basic oxygen furnace slag (BOF-S), electrical arc furnace slag (EAFS), ladle refining slag (LFS)), or by the type of steel produced in said process (carbon steel slag or stainless-steel slag) (Yi et al., 2012, Liu and Wang, 2017, Ndlovu et al., 2017). Countries such as Japan ...
The Samson feeder receives raw slag direct from the steel works for processing at an offsite crushing plant. The Samson discharges directly into a belt conveyor mounted at 90° allowing an ideal transfer onto the belt, minimising the risk of blockage as there is a high risk of oversize and tramp materials.
Electric arc furnace (EAF) slag is a by-product of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cement-based materials, due to its good physical, chemical and mineralogical properties. Particularly the re-use as coarse aggregate for concrete …
GRANULATED BLAST FURNACE SLAG (GBS) Blast furnace is an iron making unit which converts iron ore into molten iron through reduction reactions, in presence of coke and fluxes. In addition to molten iron, the furnace generates slags in …
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 use of BOF slag is its …
Coarse aggregate of BF slag for concrete mixing is produced by crushing air-cooled slag and then classifying through screens; fine aggregate is produced by lightly crushing granulated
A direct alternative to primary aggregates, slag aggregates offer versatility and most importantly sustainable solutions to standard construction products. Steel aggregates have a high abrasion and crushing resistance for road applications: air cooled blast furnace products bond particularly well to cement and bitumous binders.
