study has been conducted to explore the possibility of utilization of steel slag in concrete as coarse aggregate. After collection of steel slag aggregate from a local steel manufacturing company, the steel slag aggregate was separated into lightweight (SL), heavyweight (SH), and mixed (SM) slag aggregates.
· Experimental work was carried out to study the effect of using steel slag (SS) and recycled concrete aggregate (RCA) as replacements for the natural aggregate in concrete. Waste materials, such as SS, which is a byproduct generated during the production of steel and concrete rubble, which is produced by demolition activities, are dumped in landfill.
"The concrete made with posttreatment steel slag was about 17 per cent stronger than concrete made with conventional aggregates, and eight per cent stronger than raw steel slag." Water engineer Biplob Pramanik said the study was the first to investigate potential applications for "sewageenhanced" slag in construction material. "The global steel making industry produces over 130
The use of Steel slag concrete as a replacement to standard concretes us of recent origin. It uses largely the waste product of industries additionally to it its production needs no burning of fossils fuels therefore no emission of polluting gasses like CO2 and SO2 etc. This chapter reviews the work done by prior investigator concerning the manufacture of Steel slag concrete and its properties
concrete and natural aggregate concrete, in high strength concrete series. Slag is a waste metallic material which might have long term delayed reactions, further experiments would be necessary to evaluate the durability of concrete made by steel slag aggregates. The following size of slag available from JSW Steel Ltd,04mm,4
Use of steel slag in concrete mixtures Nasser AlNuaimi, Ramzi Ta, Abdulazeez Kilayil, and Abdelhamid Ben Salem Qatar University, Department of Civil and Architectural Engineering, Doha, Qatar Email: anasser Abstract. The recent unprecedented growth in the building industry in the State of Qatar has created a pressing demand for construction materials. Needs for concrete, being
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing
Due to the high density of steel slag, concrete containing steel slag aggregate has a higher density than plain cement concrete does . In addition, concrete containing steel slag aggregate displays satisfactory compressive strengths and flexural strengths [28–30]. Ultrigh performance concrete (UHPC) is a new type of cementbased material.
Slag Cement Benefits and Use in Concrete. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial byproduct of an iron blast furnace.
· Compared with the blast furnace slag, steel slag has the expansibility due to the reaction with water and free CaO. Therefore it is specified in Standard Specification for Concrete in Korea that steel slag aggregate must not be used in concrete. So it is unusual to use steel slag aggregate in concrete. In this study steel slag aggregate processed by several aging process was comparatively satisfied with fundamental properties as concrete
L. F. ZHANG et al.: APPLICATION OF METALLURGICAL STEEL SLAG IN ED CONCRETE METALURGIJA 60 (2021) 12, 3032 From Figure 1 that the incorporation of metallurgical steel slag has a great influence on the early strength of ed concrete, and the compressive strength declines rapidly with the increase of the content of metal lurgical steel slag. When the content of metallurgical slag
50%, and 70% steel slag into concrete by volume and tested the mechanical properties and durability of the mixture. When the cement content was 4% and the steel slag content was 50%, its strength and sti ness were the largest [14]. As a kind of high activity admixture, steel slag powder played an important role in the preparation of highperformance concrete. Compared with limestone mixture
However, since steel slag has a porous texture with multiple cracks and crevices, breakage under lower loads can be expected. In order to reduce the impact of this porous structure on strength characteristics in concrete, steel slag aggregate can be pretreated by polishing in a Los Angeles abrasion machine. This polished coarse aggregate seems to have an improved quality, with a smoother surface and
Iron and steel slag aggregate is an industrial product that is manufactured under extensive quality management, and contains no organic impurities, clay, shells, or similar materials. For both fine particles and course particles, the chemical composition is completely uniform. In addition, this aggregate contains no reactive silica, which is one cause of chemical reaction with alkali
Apr 08 2020Steel slag used in wastewater treatment has been proven to create stronger concrete than conventional concrete aggregates according to a new study from RMIT University. Steel slag is a byproduct of smelted ore and has been used as a substitute aggregate for making concrete in the past.

slag cement concretes with 30% to 65% replacement were stronger than OPC concretes after 7 to 10 days (Hogan and Meusel 1981, Meusel and Rose 1983). Fernanzez and Malhotra (1990) show that 25% slag cement replacement mix strengths are comparable to OPC at 28 days, but that 50% slag cement replacement mix strengths are lower than OPC . 1. Slag cement is often referred to as "ground
STEELSLAGS AS FILLER MATERIAL IN CONCRETE 385 Introduction In cementbased products, such as concrete and mortars, a balance between the particle sizes of the components must be kept in order to obtain the required material properties, such as workability and strength. Sometimes aggregates lack the necessary amount of fines, or the aggregates may even have been washed at the quarry or gravel
Utilizing steel slag in concrete mixes has proved to be useful in solving some of the problems encountered in the concrete industry. Steel slag was used in conventional concrete to improve its mechanical, physical, and chemical properties. Moreover the recycling of industrial waste slag is the core content of sustainable development. The only potential problem with steel slag aggregate is its

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 % compared to control mix. The study concluded that compressive strength of concrete improved by 4
the mixing ratio of a steelmaking slag for use as a concrete aggregate and the construction of concrete structures using such concrete are conducted. Specifically, steelmaking slags produced in steelmak ing refining processes have been scarcely used as concrete aggregates, unlike blast furnace slags. However, the utilization of steelmaking slags as substitutes for natural aggregates can be
