What is crushed slag? - AskingLot

08/02/2020  Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. This forces the chemical reaction to take place throughout the ore, not only at the surface.

What Are the Uses of Blast Furnace Slag (BFS)? - FTM

12/12/2019  What is the application of blast furnace slag? The blast furnace slag can be crushed and processed into blast furnace slag aggregate by roller crusher and ground granulated blast furnace slag by ball mill. These two materials can be widely used in construction, infrastructure and agriculture. Blast furnace slag aggregate

Blast Furnace Slag - an overview ScienceDirect Topics

18/10/2017  Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled. Depending on the cooling method the BFS can be produced as air-cooled, granulated, expanded and pelletized

Influence of crushed granulated blast furnace slag and ...

01/09/2019  The objective of this paper is to study the mechanical properties of marl improved with crushed granulated blast furnace slag (CGBS) activated with calcined eggshell waste.

Flux is a term ...

1. PRODUCT NAME BLAST FURNACE SLAG BASE AND SUBBASE

cooled blast furnace slag is a crushed product having angular, roughly cubical particles with pitted, vesicular surfaces. Granulated blast furnace slag has a cellular structure resulting from rapid quenching in water, is cementi-tious in nature, and sets to form a solid concrete-like mass. Applicable Standards: Air-cooled blast furnace slag

Slag aggregates - Tarmac

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. They also offer significant environmental benefits such as the reuse or
