RAPID DETERMINATION OF SULPHER IN BLAST-FURNACE SLAGS AND OPEN-HEARTH SLAGS

Blast furnace slags as sorbents of phosphate from water solutions.

The paper is focused on the sorption of phosphorus from aqueous solutions by crystalline and amorphous blast furnace slags. Slag sorption kinetics were measured, adsorption tests were carried out and the effect of acidification on the sorption properties of slags was studied. The kinetic measurements confirmed that the sorption of phosphorus on crystalline as well as amorphous slags can be desc...

Limestone Fillers Cement Based Composites: Effects of Blast Furnace Slags on Fresh and Hardened Properties

Limestone filler is a raw material that is already used in several applications like paints, bricks, bituminous mixtures...etc. Moreover, and particularly in Belgium, classical additions for concrete like fly ashes and granulated blast furnace slags are becoming rare; there is a need for new additions that could have a positive effect on the properties of the fresh and hardened cementitous comp...

Cementitious Properties of Steelmaking Slags

Microstructural Characterisation of Chromium Slags

J. Burja, F. Tehovnik, F. Vode, B. Arh, Institute of Metals and Technology, Ljubljana, Slovenia In this chromium slags that form during melting of chromium alloyed steels are examined. During melting and oxidation of these steel grades a considerable amount of chromium is lost, and gained back with slag reduction. Laboratory experiments were performed to study the mechanism of chromium oxide re...

Utilization of ironmaking and steelmaking slags

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...
