Produced during the separation of molten steel from impurities steel slag is often used as a substitute aggregate material for making concrete. Steel slag can also be used to absorb contaminants ...
Slag cement is commonly found in ready-mixed concrete precast concrete masonry soil cement and high temperature resistant building products. While there are many appli ions and benefits of slag cement a few are highlighted below and detailed information sheets are lo ed here.
The compressive strength of concrete using steelmaking slag as fine aggregates is around 1.1 to 1.3 times of common concrete. Further steelmaking slag concrete shows similar fire resistance to the river aggregate mixture up to 400 deg C and much improved fire resistance at high-temperature ranges.
Furthermore steel slag& 39;s resistance to polishing means that it& 39;s frictional benefits are maintained over time. Cement production is another area where steel slag has proven especially beneficial over other aggregates. Steel slag undergoes calcination during it& 39;s production which removes most volatile materials and CO2.
Steel slag the most discharged metallurgical slag in China is rarely applied in the production of clinkers. The aim of this study is to analyze the maximum substitution amount of steel slag in meal and calculate the resources required as well as the environmental and economic benefits of the addition.
Slag cement a byproduct of steel-making enhances the traditional concrete benefits of strength and durability while offering reductions in waste energy use and greenhouse gas emissions. Slag cement is used in concrete for virtually any construction appli ion either in conjunction with traditional portland cement part of blended cement or ...
Steel slag used as clinker meal and cement additive has proved to be feasible and efficient in resource and energy saving emissions reduction and economic benefits in cement industry. Thus there is huge advantage for China to promote the usability of steel slag in industries with a large-scale eco-industrial system especially for ...
In China BOF slag accounts for about 70% of the annual steel slag production Cheng and Yang 2010 .In the BOF process minor steel scrap and a large amount of molten iron from ironmaking as well as fluxes lime/dolomite are added into the furnace and a 99% pure oxygen flow is applied at supersonic speed through a lance to initiate intense oxidation reactions at a temperature of 1600 ...
