solid wastes in steel plants are essential by-products generated during various processing steps involved in the production of iron and steel. solid wastes generated by integrated iron and steel works cause environmental pollution and therefore must be discarded. until the last decade, the slag, dust and sludge generated by integrated steel plants was called waste', but now this term has been replaced with “by-product” due to intensive re-utilization of these wastes.,mechanical properties of concrete using steel slag aggregate,shrinkage of steel slag exposed to a dry environment was similar to limestone aggregate. 1.5 objecttives the objective of this research was to find combined aggregate gradations, using steel slag aggregate, which will significantly reduce the amount of cement required by 10% to 15% without compromising concrete properties.
in this research industrial waste slag from a local steel mill, namely mangla metals was selected as possible replacement of cement. some preliminary standard tests conducted on the slag showed its strong chances to be used as pozzolana. slag used for this study was reduced to the particle size passing through astm standard sieve #100.,durability studies on steel slag concrete and comparison,this is an experimental project which deals with the studies on the durability of steel slag as replacement of coarse aggregate in concrete. this project outlines the method of preparation, testing procedure and salient results on the concrete that is manufactured using the waste products of steel industries. in this project, concrete of grade m40
about 100–150 kg ss is co-produced for 1000 kg steel, and a huge amount of slag storage is generated annually worldwide. despite the problems associated with ss, this storage should be evaluated for sustainable development, and it has many possibilities for use in the cement and concrete industry (lizarazo-marriaga et al. 2011).millions of tons of ss are produced in iron and steel factories,an overview of utilization of slag and sludge from steel,significant quantities of sludge and slag are generated as waste material or byproduct every day from steel industries. they usually contain considerable quantities of valuable metals and materials. it is generally possible to recover some values by physical or chemical mineral processing techniques such as crushing, grinding, classification, hydrocyclone, magnetic separation, flotation,
steel slag can also be used to absorb contaminants like phosphate, magnesium, iron, calcium, silica and aluminium in the wastewater treatment process, but loses its over time.,concrete using wastes like slag from steel industries,the experimental results show the application of steel slag sand may reduce the dosage of cement clinker and increase the content of industrial waste product using steel slag sand. isa yuksel, omer ozkan, turhan bilir, 2006  experimented use of non ground granulated blast furnace slag as fine aggregate in concrete.

slag for its utilization in cement industry . use of steel slag once considered as waste material it has now become a use-ful raw material for many industries and is almost 100% utilized in some part of the world. us, europe and other developed countries utilize up to 70–80% of the slag it gen-,concrete made with post-treatment steel slag is stronger,the concrete produced using post-treatment steel slag was about 8% stronger than raw steel slag and 17% stronger compared to concrete made using traditional aggregates. according to dr biplob pramanik, a water engineer, the study was the first to examine prospective applications of “sewage-enhanced” slag in construction material.
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,making stronger concrete with ‘sewage-enhanced’ steel slag,the concrete made with post-treatment steel slag was about 17% stronger than concrete made with conventional aggregates, and 8% stronger than raw steel slag. water engineer dr biplob pramanik said the study was the first to investigate potential applications for “sewage-enhanced” slag in construction material.
the concrete made with post-treatment steel slag was about 17% stronger than concrete made with conventional aggregates, and 8% stronger than raw steel slag. water engineer dr biplob pramanik said the study was the first to investigate potential applications for “sewage-enhanced” slag in construction material.,concrete strengthened with 'sewage-enhanced' steel slag,“steel slag is currently not in widespread use in the wastewater treatment industry—just one plant based in new zealand uses this by-product in its treatment approach,” he said. “but there is great potential here for three industries to work together – steel making, wastewater treatment and construction—and reap the maximum benefits
steel slag to know whether or not they can fulfill the properties of cement and sand. 2) to investigate the compressive, tensile, and flexural strength of concrete using steel slag as fine aggregate and blast furnace slag as cement. 3) to find out the optimum replacement level of steel slag and ground granulated blast furnace slag 2. literature,the effect of replacing sand by iron slag on physical,crushed rocks andiron slag.steel slagis a material which could be used as a partial replacement for ﬁne aggregate . the con-sumption of waste materials can be increased manifold if they are used as aggregates in both cement mortar and concrete. these types of uses of waste
in this way, we are going to utilize steel slag and silica fume which is a modern by product acquired after the generation of steel and silicon metal individually. the production of steel is connected with the liberation of solid waste materials like slag. the generation of solid waste,research targets linking steel slag recycling applications,research targets linking steel slag recycling applications - recycling today. magnified images showing concrete made with treated slag (center), conventional aggregates (left) and raw slag (right). the treated slag forms a more seamless bond with the cement paste, making the concrete stronger, according to an australian university.
like other industrial byproducts, slag actually has many uses, and rarely goes to waste. it appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer. firstly, slag represents undesired impurities in the metals, which float to the top during the smelting process.,comparison between utilization of industrial waste steel,the higher unit weight of the steel slag coarse aggregate concrete attributes to higher speciﬁc gravity of the steel slag coarse aggregate . the main objective of this paper is the comparison between utilization of industrial waste steel slag as aggregate and natural aggregate (crushed dolomite and gravel) in underwater self-compacting
