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

various replacement level of steel slag with fine aggregate. The use of steel slag aggregates in concrete by replacing natural aggregates is a most promising concept. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance. II. MATERIALS USED

This paper describes the work carried out in laboratory to produce concrete with good properties using oxidizing electric arc furnace (EAF) slag as fine and coarse aggregate. To do this, the slag ...
nace without the production of its co-product i.e. blast furnace slag. 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
The use of steel slag in paving mixes should be limited to. replacement of either the fine or the coarse aggregate frac -. tion, but not both, because hot-mix asphalt containing 100%. steel slag ...

concrete using steel slag as the fine aggregate replacement. To conduct a comparative study on steel slag, fiber in steel slag and conventional concrete. 4. Methodology The methodology of the work consist of . 1) Identifying the specification of material to be selected. 2) Collection of materials such as polypropylene fiber and steel slag.
The use of steel slag as fine aggregate in concrete mixes has a positive effect on both compressive and tensile strengths; hence introducing it in concrete will eliminate one of the environmental problems created by the steel industry. 3. Best results for the enhancement of compressive strength are obtained when the replacement percentages are ...
It can be used in concrete mixes, asphalt concrete (AC) mixes, and soil stabilization.Steel slag can be processed into coarse or fine aggregate material for use in dense-graded and open-graded hot-mix AC pavements (Norton 1979;Kandahl and Hoffman 1982;Rossini-Lake et al. 1995) and in cold mix or surface treatment applications (Noureldin and ...
study of partial replacement of natural fine aggregate by steel slag and natural coarse aggregate by waste limestone aggregate in M20 grade of cement concrete. Steel slag is a waste by-product obtained from the iron and steel plants and waste limestone aggregates are the waste broken pieces of
1. The use of steel slag increases the compressive strength of concrete by a maximum of 1.3 times the strength of normal concrete, depending on the ratio used. However, reduction in strength can occur beyond the 50% replacement ratio. 2. The optimum value occurs when the sand is replaced by 15 to 30% slag.
since they show that using steel slag as fine aggregate in concrete has no negative effects on the short term properties of hardened concrete. So Steel slag meets the requirements to be used in concrete mixes. Compressive strength, flexural strength and splitting tensile strength for steel slagaggregates
Qasrawi et al.13 found that the use of steel slag as fine aggregate in concrete mixtures increase compressive and tensile strength of concrete. Pellegrino and Gaddo2 investigated the feasibility of use of steel slag for natural aggregate replacement in concrete and found that concrete produced with steel slag aggregate
Apr 20, 2019 To alleviate the supply problem of natural sand, searching for sand substitutes in concrete is necessary. In the engineering field, the use of steel slag in concrete as a fine aggregate has been reported in recent studies. Qasrawi et al. pointed out that the use of steel slag as a fine aggregate in concrete mixes is a promising technology. Their experimental results indicate that using steel slag as a fine aggregate has a positive effect on both the compressive and tensile strengths of concrete.
Dec 20, 2018 The use of steel slag as aggregate in concrete is a sustainable solution for reducing serious impact on the ecological environment caused by the shortage of natural mineral resources. This paper presents the first ever study on the behaviour of steel slag sand concrete (SSC) under axial impact compression.
Jan 01, 2021 The use of steel slag prevents a growth of calcium hydroxide around the fine aggregate particles and prevents the formation of ettringite (sulfate calcium sulfoaluminate). Therefore, these mechanisms improve the concrete as resistance of concrete to acid attack.
