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 (ACW14 and ACB28).
replacement of fine aggregate using steel slag was adopted to be 60 percent. Dolomite based concrete mixture was studied as a reference mixture and the results revealed that the mechanical properties of concrete made with steel slag aggregate are comparable to that of dolomite concrete up to the temperature of 550°C. The
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
Other uses Include, skid resistant asphalt aggregate, rail ballast asphaltic concrete aggregate, soil conditioner, hard stand areas and unconfined construction fill. Electric Arc Furnace Slag (EAF or steel furnace slag) Produced when scrap metal and fluxes are oxidized by the use of an electric current. Molten slag is generally placed into ...
Ferrous slag is a by-product of the iron and steel making process. Steel cannot be prepared in the Basic Oxygen Furnace (BOF) or in an Electric Arc Furnace (EAF) without making its by-product, steel slag. 1. The use of ferrous slag aggregate in concrete by replacing fine aggregate is .
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
replacing aggregates with steel slag - shibang-china. The effect of recycled concrete aggregate and steel slag on, properties of asphalt mixtures with waste concrete and steel slag aggregates. of steel slag. Get Price The effect of replacing sand by iron slag on physical.
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 ...
has generated substantial solid waste. Steel slag is a residue obtained in steel making operation. This paper deals with the implementation of Steel slag as an effective replacement for sand. Steel slag, which is considered as the solid waste pollutant, can be used for road construction, clinker raw materials, filling materials, etc.
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 [9] in-vestigated the possibility of using a carbonated LF slag as a fine aggregate in concrete. The slag was treated with CO. 2
whereas large steel slag deposits are locally available. The primary aim of this research was to evaluate the durability of concrete made with steel slag aggregates. This research has shown that replacing some percentage of natural aggregates by steel slag aggregates causes negligible degradation in .
The two types of concrete aggregate that are manufactured using iron and steel slag as a raw material and which are covered by JIS standards are blast furnace slag aggregate and electric arc furnace oxidizing slag aggregate. Each of these types includes course aggregate and fine aggregate.
items containing steel slag, and is one motivation behind why steel slag aggregate are not utilized as a part of concrete development. The present research work deals with a view to develop efficient concrete by addition of steel slag to evaluate the effectiveness of the use of steel slag as a partial replacement in sand To replace Sand
Abstract An experimental work was carried out to study the effect of Energy Optimizing Furnace (EOF) steel slag as coarse aggregate replacement in concrete. Surface modification of slag was carried out to seal the surface voids of raw slag aggregates. Quarry dust obtained as an extractive waste from the granite stone quarries has been used as a blending material in this work.
This paper aims to study experimentally, the effect of partial replacement of coarse aggregate by steel slag (SS), on the various strength and durability properties of concrete, by using the mix design of M40 grade. In this study, steel slag was used
steel slag concrete for 0%, 10%, 20%, 30%, and 40% replace-ment of fine aggregate by steel slag. The concrete specimen cubes are cured in normal potable water for 14 and 28 days. Then tests will give us results of variations in ive compress strength and these variations can tively shown bybe effec graphs below. 3. A. DMIXTURES. STEEL SLAG
In this concrete. aspect steel slag has become a viable option as a Tarek et al. [3] compared the physical and mechanical replacement for coarse aggregates in concrete properties of lightweight, heavyweight and mixed weight production. slag aggregates with that of common brick aggregates.
Study on replacement of coarse aggregate by steel slag and fine aggregate by manufacturing sand in concrete Article (PDF Available) in International Journal of ChemTech Research 8(4):1721-1729 ...
Steel slag aggregate (SSA) is a byproduct of the production of steel in an electric arc furnace. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense (SSA is 20-30% heavier than naturally occurring aggregates such as basalt and granite).
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
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.
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
