Granulated blast furnace slag is a waste of steel industry; its use can be best exploited as part replacement of sand in concrete. It can replace sand to the amount of 70 % in concrete mixes. Its Availability is limited, restricted to steel plant area.
The replacement of 40% steel mill scale with that of fine aggregate increased compressive strength by 40%, drying shrinkage was lower when using steel mill scale. Sean Monkman, Yixin Shao, Caijun Shi, 2009 [9] investigated the possibility of using a carbonated LF slag as a fine aggregate in concrete.
order to maintain the workability of the mix. It was seen that concrete mix having water/cement ratio of 0.55 and 0.65 resulted in high water consumption and greater compressive strength. The significance of this study is to use steel mill scale as replacement of sand, providing an environment friendly solution for waste management.
The hydraulic and pozzolanic properties of fly ash and slag make them a suitable alternative for cement replacement. Several studies have been done in the past to confirm the suitability of fly ash in cement mortar and concrete,, . Use of slag in mortar and concrete is also been studied extensively by many researchers,,, .

Further, iron, alumina and silica are essential ingredients in cement and aid in the formation of C2S, C3S, C4AF and C3A, which in turn provide strength characteristics to concrete. Hence, the partial replacement of fine aggregate by mill scale in concrete can be attempted. REFERENCES 1. International Iron and Steel Institute. (1987).
PAT - BLAST - Medium grade coal slag abrasive is used for general purpose applications. Removal of mill scale, rust and paint stripping on structural steel, ships, bridges. PAT - BLAST - Fine grade coal slag abrasive is used for light paint and rust removal and new construction application.
Abstract-This research exploits ground granulated blast furnace slag (GGBFS) as a replacement of sand on the physico-mechanical properties of concrete. Using these natural materials helps in the natural exchequer such as aggregate and cement. In addition to, it also helps in reducing the cost of manufacturing concrete.
studied on replacement of sand by steel mill has concluded that 40% replacement of sand with steel mill scale gave the highest increase in compressive strength. Li Yun feng (2009) found that concrete with good performance can be produced using mineral admixtures consisting of steel slag powder and blast furnace slag. In the present paper an ...
Materials. Five types of cementitious powders were used in this study, including a type I ordinary Portland cement (ASTM C150), a grade 100 (ASTM C989) ground granulated blast-furnace slag, a class F fly ash (ASTM C618), recycled soda-lime glass powder (GP) and reagent calcium hydroxide powder (Ca(OH) 2 or CH). Slag is an angular shaped powder …
For this present study M20 grade concrete shall be designed, Partial replacement of sand with steel slag will be made for varying percentages such as …
M20 grade concrete with the replacement of sand by steel mill scale waste and granite powder waste from 10% to with the increments of 10%.This paper presents a detailed experimental study on compressive strength, bulk density, and water absorption of the M20 grade concrete containing steel mill scale and granite powder.
A method is provided for manufacturing cement from a raw material mixture which includes finely ground steel slag. Selected quantities of steel slag and other raw materials are mixed with each other and supplied to a raw mill. The steel slag and other raw materials are preferably ground to a fine, dry powder. For some applications, the dry powder is preferably supplied to a blend …
This paper emphasizes on the use of material to be replaced by natural sand which will give new dimension in concrete mix design and if applied on large scale would revolutionize the …
Concrete mixes that were produced for this work contained iron ore, steel mill scale, two types of barite, and steel slag, which are the heavyweight aggregates available in Turkey. An additional heavyweight concrete mixture was also produced using magnetite as a natural mineral heavyweight aggregate.

Compressive strength increased by 40% in case of replacement of 40% steel mill scale with that of fine aggregate, drying shrinkage was lower when using a steel mill scale. Sean Monkman et al [12] investigated using a carbonated LF slag as a fine aggregate in concrete.
Coal Slag Ab Deburring. Coal slag abrasives offer superior cleaning ability thanks to hard angular particles that enhance speed and cutting Coal slag is a preferred alternative to silica sand which can contain up to 99 free silica and has been found to cause silicosis a sometimes fatal lung disease Less than 01 free silica Low dusting Chemically inert.
The study concluded that compressive strength of concrete improved almost all the % replacements of normal crushed coarse aggregate with crystallized slag by 5% to 7%. In case of replacements of fine aggregate and both type of aggregates, the strength improvements were notably noticed at 30% to 50% replacement level.
Copper slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-2 and SA-2. Copper slag blasting media/grit is manufactured of the granulated slag of copper refineries, and used for blast-cleaning of metal surface.
The use of alternative fuels in both combustion and production processes is known as co-processing in cement manufacturing. Waste is now being used to substitute primary fuel sources like coal, petroleum, and gas in the combustion process. They are usually from combustible municipal waste, refuse-derived fuels, biomass, or non-hazardous industrial and commercial …

Use of Slag. Slag plays an important role in industrial production, especially in some large factories, slag is extracted and processed into slag cement, slag fine powder, slag powder, slag Portland cement and slag cotton. Blast furnace slag can also be used as raw materials for cast stone, glass-ceramic, fertilizer, enamel, ceramics and so on.
