The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity of the paste containing The construction industry is the largest consumer of natural resources which led to depletion of good quality natural sand (Fine aggregates). This situation led us to explore alternative materials and granular slag a waste industrial byproduct is one such material identified for utilization it as replacement
the possibility of used of steel slag in road pavements. This paper focuses on the use of steel slag as partially replacement in bituminous mix as coarse aggregate with 10 %, 20% and 30% Steel Slag Proportion by weight of total weight of Mix. Key words: Steel Slag, Solid Waste, Bituminous Mix,
with the iron slag replacing 10 %, 20 % and 30 % of fine aggregates with the same amount of cement, coarse aggregates and same water cement ratio. The curing period of all the concrete mixes was 7, 28 and 56 days. Figure 3.1 Dry mix of cement, sand, aggregate and iron slag
(2) Granulated slag is the glassy, granular product formed when the molten blast furnace slag is rap-idly chilled by immersion in water. Basic Use: Aggregates are used for all types of base and subbase construction. In addition to applications requiring graded aggregates, pit run blast furnace slag is extensively used for subbase
tocodal provisions IS 2386:1963and the results are The results showed that replacing about 60 percent of given in tables. steel slag aggregates for coarse aggregate and 40 Steel slag: The steel slag used here is an air cooled percent of ecosand for fine aggregate will not have any slag and is collected from Dennis steel plant at adverse effect
Jan 16, 2017Partial replacement of Fine aggreggate by Copper Slag and Cement by Fly Ash 1. 1 Replacement Of Fine Aggregate By Copper Slag And Cement By Fly Ash Ammini College Of Engineering, Mankara, Palakkad 1. INTRODUCTION 1.1 GENERAL Concrete is the man made material widely used for construction purposes.
Recycled materials in the building industry represent an attractive alternative to the consumption of natural resources. The paper shows results obtained by adding electric arc furnace slag (EAFs) as partial replacement of natural aggregates in concrete production.
STEEL SLAG: Steel slag are the industrial by-products from a greatest interest to the pavement construction industry but minimum of slag will be introduced in concrete replacement as cement. In this project 5%-10% of steel slag are replaced as cement. The chemical composition is mentioned below in table A. Table A.

Converting Granulated Blast Furnace Slag into Fine Aggregate 93 Fig 1: BF Slag Granulation PROBLEM Granulated blast furnace slags are available with steel industry for decades but were never accepted as a fine aggregate in construction activities till this developmental work.
Mechanical Properties Of Concrete Using Steel Slag Aggregate Page | 9 improvement in compressive strength, split tensile and flexure strength over control mixes by 4 to 8 %. The replacement of 100 % slag aggregate (coarse) increased concrete density by about 5 to 7 %
This test is conducted by replacing steel slag at a level of 10%, 20%, 30% and 40% after 7, 14, 28 and 50 days of curing for an M35 grade of concrete. Table 5.Avg.Tensile strength test results for M35 grade of concrete Sr. No Percentage Replacement of Fine Aggregate by Steel Slag Average Flexural Strength for M35. (N/mm 2) 28 DAYS 1. 0% 4.073
The replace-ment 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  in-vestigated the possibility of using a carbonated LF slag as a fine aggregate in concrete. The slag was treated with CO. 2
being precalcined, slag cement saves up to one ton of co2 for each ton used slag saves energy because it is 15% lighter than comparable natural aggregates replacing natural aggregates with slag minimizes utilization of non-renewable resources slag acts as a natural insulator, increasing energy efficiency in building products
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel. Steel slag
Granulated blast furnace slag; 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.
in an Electric Arc Furnace (EAF) without making its by-product, steel slag . The use of steel slag aggregate in concrete by replacing natural aggregate is a most promising concept . Steel slag aggregates are already being used as aggregates
66.67% steel slag aggregates as a replacement of the coarse aggregate. Qurishee et al.(2016) in their experimental study on the use of slag as coarse aggregate and its effect on mechanical properties of concrete. It was reported that compressive strength of concrete made by replacing coarse aggregate with slag is higher than normal conventional
Sand For Concrete From Steel Mills Induction Furnace Waste Blast furnace slag is used in blended cement. Although many studies have been conducted on the evaluation of the electric arc furnace slag to be use in concrete as aggregates replacing natural aggregates, no studies have been performed regarding the use of induction furnace slag in concrete as aggregates replacing natural aggregates.
replacing fine aggregate with waste materials. In this present study blast furnace slag from two sources were replaced with fine aggregate and the properties of concrete were studied. The optimum percentages of replacement of these materials were found out. The result obtained encourages the use of these materials as
1. PRODUCT NAME 2. MANUFACTURERS Producers of steel furnace slag aggregates for base course and subbase construction (applicable under either rigid or flexible pavements) can be contacted by visiting the NATIONAL SLAG ASSOCIATION at 3.PRODUCT DESCRIPTION Composition: Steel slag is the by-product of steel making.
This paper aims to study experimentally, the effect of partial replacement of coarse and fine aggregates by steel slag (SS), on the various strength and durability properties of concrete, by using the mix design of M20 grade. The optimum percentage of replacement of fine and coarse aggregate by steel slag is
The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance
Steel slag, a by-product of steelmaking, imposes lots of negative impacts on the environment. For alleviating negative impacts, more and more experiments have been carried out to explore the application possibility of steel slag. The purpose of this study is to explore the feasibility of steel slag being applied in induction healing asphalt concretes to replace coarse and fine aggregate.
