Fingerprinting South African Cements

With the trace elements available from the cement input materials and the cement itself, it was possible for the individual granulated blastfurnace slag, fly ash and limestone. Slag is sourced from four sources. Plant C uses the entire arisings from one of the sources, leaving three sources for

Is steel slag safe?

Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material. and granulated slag have also been used as sand blasting shot materials. based on trace element chemistry, principally for base metals. Both types of slag have been a source of some environmental contamination.

Aug 01, 2016Aug 01, 2016In blast furnace slag cement with a ground-granulated blast furnace slag concentration of 35 wt% they found the concentration of alkali elements in pore solution to be decreased by 40%–45% compared to CEM I. The CEM III/B cement used in this study contains about 67 wt% blast furnace slag.

Leaching behaviour of major and trace elements from

The leaching of major and trace elements from concrete made with Portland cement, fly ash and GGBS (ground granulated blast-furnace slag) was studied using pH static availability and tank leach tests. The release of substances during the tank leach test occurs by surface dissolution of phases at the concrete surface and diffusion inside the

Removal of sulphates from aluminium powder coating

sulphates from APCE using Basic Oxygen Furnace Slag (BOFS) and Granulated Blast Furnace Slag (GBFS) as an adsorbent. BOFS was used as the basis of all the experiments as it increased (Cr3+) which is a trace element for humans and animals. The use of sodium metabisulphite is an easy process for reducing chromium [5].
