In the current study, Replacement of ferrochrome slag with conventional coarse aggregate in concrete for high strength (M50 Grade) concrete for every incremental of 25% replacement upto is done.

The importance of using the right type and quality of aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ ence the concrete's freshly mixed and hardened proper ties, mixture proportions, and economy. Fine aggregates (Fig.

strength and the final attainment of strength in concrete containing steel slag with OPC+GGBS is relatively high compared to the samples containing River sand and M sand with OPC+GGBS. Which shows that concrete containing steel slag as the fine aggregate of low strength gains higher

As an example, The Ark project, a high rise commercial building in Sydney, was constructed using concrete made with industrial biproducts such as fly ash, ground granulated blast furnace slag and air cooled slag aggregates to successfully achieve specific 'Green' criteria.

Study on Strength Properties of Concrete by Partially Replacing Fine Aggregate as Steel Slag J. Vidhya, R. Dhilipkumar Assistant Professor, The Kavery College of Engineering, Mecheri,Salem Abstract—Most of the volume of concrete is aggregates. Replacing all or some portion of natural aggregates

The ordinary fine aggregate in concrete has been replaced by ground and sieved steel slag fine aggregate, treated and exposed to air for three months. Compared with concrete made from natural sand, properties such as compressive strength, flexural strength, elastic modulus, permeability and abrasion resistance are considerably improved.

Key words: steel slag aggregate, artificial sand, OPC, compressive strength, coarse aggregate. INTRODUCTION Conventionally concrete is mixture of cement, sand and aggregate. Properties of aggregate affect the durability and performance of concrete, so aggregate is an essential component of concrete.

slag are also used. There are other classes of nonstructural lightweight concretes with lower density made with other aggregate materials and higher air voids in the cement paste matrix, such as in cellular concrete. These are typically used for their insulation properties. This CIP focuses on structural lightweight concrete. The primary use ...

A spectacular addition to the Interstate 90 corridor, the headquarters features many sustainable construction materials that contributed to LEED® certification, including the NewCem® Slag Cement and True Lite Lightweight Aggregate™ used in the 59,000 cubic yards of highperformance concrete for the structure's foundation, floors and ...

n Dry process, where the crumb rubber is added to the aggregate prior to the addition of the asphalt concrete. n Terminal blend process, where the rubber is added to the asphalt concrete at the bitumen refinery. The current use of scrap rubber in Australia is in specialised sprayed bitumen seals for .

Slag: The AllPurpose Aggregate. In fact, this product can be recycled into valuable, versatile construction materials for green use. We utilize slag, a product of steelmaking, in versatile construction material for environmentally beneficial use. Applications include road construction, asphalt, readymix concrete, cement, railways ballast, mining, filtration and agriculture.

Steel furnace slag is a coproduct of the steel making process and Edw. C. Levy Co. reclaims this as a costeffective and durable aggregate for road building. Duraberm, which is made from steel furnace slag, is a strong and sustainable material that holds up under heavy truck traffic, provides long service life, and helps control project cost.

BROADER USE OF STEEL SLAG AGGREGATES IN CONCRETE JIGAR P. PATEL ABSTRACT Steel slag is an industrial byproduct obtained from the steel manufacturing industry. It is produced in large quantities during the steelmaking operations which utilize Electric Arc Furnaces (EAF). Steel slag can also be produced by smelting iron ore

silicate ISF slag from zinc production as aggregates bound in cement or bitumen. Additionally, laboratory studies at BRE showed the technical feasibility of using these waste streams in construction.

results of these tests showed that concrete made from slag has almost the same compressive strength as concrete in which natural sand is used. In addition, the drying shrinkage rate and freezethaw resistance, which are values related to the durability of concrete, of such slag concrete did not show
