The waste is a spent grit used for sand blasting in the cleaning operations of tankers in the dock yard. This paper presents the modified properties (chemical composition, the shape and size of the particle) of the steel grit during the blasting process and the possibility of recycling the waste as a fine aggregate in the road construction ...
Recyclable foundry residues includes substantial proportions of slag from non-ferrous metallurgy and from stainless steel production. Slags are formed as waste or by-products of metallurgical smelting processes and are created from largely homogeneous smelts that consist of free or bonded oxides.

slag used for this purpose. • Pelletised or expanded slag has a vesicular texture (like volcanic rock) and is most commonly used as a lightweight aggregate. If finely ground it also has cementitious properties. In some countries, up to 80% of the cement contains granulated BF slag.5 Using slag prevents it going to landfill as waste, saves

Jul 01, 2016· Steel slag and waste glass have the potential to improve the fire resistance of concrete. It should be noted that the current research is only conducted at macroscopic scales to investigate the influence of steel slag and waste glass on the mechanical properties and fire performance of concrete.
Steel slag, a waste product of steel yield has been used widely in road construction, because it has similar hardness to those typical coarse aggregates. Sustainability is an important aspect of developed countries, and the transportation industry is constantly trying new and innovative ways to recycle materials. Steel slag is the outcome of
The advances in steel slag have changed since dumping waste where ever someone saw fit. There are countless possibilities for what steel slag can be recycled into; from construction material to submerged arc welding flux. Doing this helps the environment, which is just as important as making a profit for a company, probably even more.
Vacuum improves both the green and cured product strength and binder effect. The lower levels of binder and moisture required permit more metal recovery from slag and other steel production residues — with individual waste streams converted .

New Zealand Steel operates a landfill for unwanted materials that are not hazardous. (Hazardous materials are taken off-site for treatment by a specialist Auckland company.) About 140,000 tonnes of waste is deposited into the steel mill's landfill each year.
History of Steel Manufacturing in Australia . Steel manufacturing in Australia has had a chequered history. Following the discovery of deposits of iron at Iron Knob, SA, in 1840, the industry had an inauspicious start, with several unsuccessful attempts to produce pig iron and steel in South Australia, Victoria, New South Wales and Tasmania.
New Zealand Steel approaches solid waste management by following the principles of avoid, reduce, reuse, recycle. If waste generation cannot be avoided, the best way to deal with it is to lessen the amount created and then find positive ways to reuse and recycle any remaining waste.
Waste slag as alternative raw material in the cement production . Ferrous slag is produced by adding slagging agents such as limestone or dolomite and/or fluxing materials to blast furnaces and steel furnaces to strip the impurities from iron ore, steel scrap, and other iron or steel input feeds.
