A Study of Alternative Construction Materials for Slag Derived from Steel Making Industry. ... Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable ...
Slag aggregate is a sustainable and cost-effective alternative to natural stone. This high-performing aggregate is hard and durable, with the additional benefit of draining well. Due to its cubical shape, the slag aggregate locks together which makes it an excellent candidate for construction applications.
· As natural aggregate sources are becoming depleted due to high demand in road construction and the amount of disposed waste material keeps increasing, researchers are exploring the use of alternative materials which could preserve natural sources and save the environment. In this study, steel slag was used as an aggregate replacement in conventional dense graded asphalt mixes …

Finely ground slag may be blended with portland cement or added to other ingredients at the mixer. When slag, a by-product of the iron-making process, is quenched with water and rapidly chilled, it forms a glassy granulated material of sand-like consistency. Because of its high calcium silicate content, it has excellent cementitious properties.
· Hence slag was a better alternative to river sand, which has become scarce since the Supreme Court banned the extraction of river sand, they said. Microscopically, river sand and …
· Historically, slag has been used for the construction of roads and as filler material. However, more recently, slag uses have been expanded to include use as a cement additive, landfill cover material, and for a number of agricultural and construction applications (Proctor et al. 2000 ).
Construction equipment needed to properly place and compact bottom ash or boiler slag in an embankment or structural backfill includes a bulldozer for spreading the material, a compactor, either a vibrating or pneumatic tired roller, a water truck to provide water for compaction and to control dusting, and a motor grader where final grade ...
steel slag was investigated for their suibilittay in road pavement, while copper tresses aslag and zinc slag may be used as a partial replace ment of fine aggregate for the construc-tion of sub base, base and bituminous layers. The specific gravity of copper slag, zinc slag and steel slag …
· Slag. Depending on where you''re from, it may be an insult, a term meaning trash, or, in our case, the waste left over from metal smelting or refining. Outside of the construction industry, it might seem that uses for slag are considered limited.
Especially (2005) that the construction cost of road base can reduced by the Europe, Canada, Australia and USA have not treated it as an use of cement activated steel slag with natural soil mix, because industrial waste but a useful construction material, and it provides maximum strength and stability with a shorter successfully using steel ...
Another way to say Construction? Synonyms for Construction (other words and phrases for Construction).
Alternative Raw Materials for Cement. Steel manufacturing by-products such as Electric Arc Furnace slag, Ladle Furnace slag and mill scale are valuable secondary raw materials for the cement industry. Under the Circular Economy context, industrial waste and byproducts should be first considered as secondary raw materials or alternative fuels ...
· Alternative cements (inorganic cements that can be used as complete replacements for portland or blended hydraulic cements) include geopolymers, activated glassy cements, activated fly ash cements, activated slag cements, calcium aluminate cements, calcium sulfoaluminate cements, magnesia cements, CO2-cured cement, and more.
The 2015 recovery quantities for blast furnace slag are shown in Fig. 15. Granulated slag makes up 86 %, of which almost the entire amount is used in the cement industry. The fields of application of the air-cooled slag are mainly in road construction and other uses in the construction industry. 4 Trends in slag recycling
· Slag contain free lime (CaO) and magnesium oxide (MgO) in very small amount that can cause volumetric instability in concrete. However, such risk can be mitigated by stockpiling and sufficiently exposing the slag materials in an open environment to weathered for a long period of time before usage [33,39].Some of the common chemical oxides composition in steel slag are SiO 2, Fe 2 …
Sustainable construction alternative for Portland Cement. GGBS is an environmentally friendly product and made from a by-product of iron manufacturing. It is a high quality, low CO 2 material. Because GGBS has low embodied CO 2, it allows designing concrete mixes for sustainable construction.

Addendum (Addenda) Written information adding to, clarifying or modifying the bidding documents. An addendum is generally issued by the owner to the
Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel.The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.
While alternative construction materials derived from slag are not as versatile as sand, slag is a high-quality construction material for car parks, noise barriers for motorways and similar construction projects. The C.C. Group. is experiencing an increase in the demand for slag by the construction …
· The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable development, and in the same time, it is matching with the cost concern of the present materials. Copper slag is a by-product obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road ...
Granular Slag - Potential Sustainable Material Alternative to Fine Aggregate in Construction Applications Mohd NADEEM 1,♠, Arun D.

produced. The slag is highly stable and non-leachable in nature. With increasing scarcity of river sand and natural aggregates across the country, construction sector is under tremendous pressure to explore alternative to these basic construction material to meet the growing demand of infrastructure demands.
Fine Copper Slag as an Alternative Marginal Material for Road Construction. Fine copper slag is a waste material generated during the extraction of copper form its ore. This slag was investigated for its suitability in the construction of embankment and different pavement layers.
increasing day by day there is a need to find the new alternative material to replace the river sand, such that excess river erosion and harm to environment is prevented. In present study alternatives of natural sand, blast furnace slag were evaluated for their suitability of …
Copper slag is a by-product formed during the copper smelting process. The molten copper forms at the bottom of the furnace while molten slag is formed on top. The molten copper slag is then drained off and quenched with water or left in the air to cool. In Singapore, treated and processed copper slag (Mohs Hardness ≥6) is imported from various
· B last Furnace Slag. Just like fly ash, blast furnace slag is a byproduct that can be recycled and used to make an environmentally friendly alternative to concrete. This glassy granular material is produced by quenching molten iron slag from the blast furnace into water or steam.
Concrete without Cement – A Green Alternative Fly Ash. Concrete without cement is possible with the use of fly ash as an alternate for cement. It matches both the chemical and physical properties of cement. Thus it has the ability to replace cement completely. The word "concrete" defines as the bonding between aggregates, cement and water.
