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 2030% heavier than naturally occurring aggregates such as basalt and granite).
In this study an attempt is made to use steel slag, a byproduct from steel industry as replacement for coarse aggregate in concrete and eco sand which is a commercial byproduct of cement ...
Partial Replacement of Fine Aggregate by using Steel slag in concrete, 1Lecturer senior Grade, Department of Civil Engineering, Nachimuthu Polytechnic College, Pollachi 2Lecturer, Department of Civil Engineering, Nachimuthu Polytechnic College, Pollachi AbstractConcrete is a widely used material in the world.
concrete using BF slag as aggregate. Thereafter, the aggregate use of BF slag expanded, and in 2013, the use of fine BF slag aggregate ... The measures to solve the problems in the use of fine slag aggregate for con ... 20cm thick beds of iron/steel slag 2) Concrete mixing According to No. 3 in Table 5 3) Outlines of paving work ...
about 0%, 25 % and 50% of steel slag aggregates by that of fine aggregate will not show any harm and any adverse effect to the durability and strength. The test is carried out after 7 and 28 day of curing. OBJECTIVES To determine the optimum quantity of steel slag as a fine aggregate to enhance the strength of concrete by conducting
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 .
Mar 18, 2011· Abstract. This paper aims to investigate the possibility of utilizing steel slags produced in Croatian plants as a concrete aggregate. Aggregate properties were determined on coarse slag fractions (4–8, 8–16 mm) according to the relevant European Standards.
Aggregates for Concrete bination of gravels or crushed stone with particles ... blastfurnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the ... and steel punchings or shot are used to produce heavyweight concrete and radiationshielding concrete (ASTM C 637 and C 638). ...
flexural properties of concrete containing steel slag are compared with that of concrete containing river sand and also manufactured sand. But in this paper only the effect of using granulated steel slag in concrete mixes as an fine agate on compressive strength and workability is discussed.
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. The
The applications of steel slag powder and steel slag aggregate in ultrigh 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 ...
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 ...
concrete. Results concluded that the use of the steel slag as fine aggregate had a negative impact on the workability of concrete, but it had positive effect on mechanical properties, and the best results of compressive strength were obtained as the steel slag content was 15% and 30%. The steel slag aggregate produced by a steel plant is also ...
This report presents available information regarding the use of aircooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. The report discusses ACBFS aggregate production and properties, and the properties of concrete produced with ACBFS coarse aggregate. Both the .
Steel slag is currently used as aggregate in hot mix asphalt surface applications, but there is a need for some additional work to determine the feasibility of utilizing this industrial byproduct more wisely as a replacement for both fine and coarse aggregates in
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
In this study, the use of steel slag as fine and/or coarse aggregate in concrete is investigated. For this purpose, 12 different concrete mixtures with different water/cement ratios of, and which include steel slag aggregate as fine and/or coarse aggregate are prepared.
INTRODUCTION. Steel slag can be processed into a coarse or fine aggregate material for use in dense and opengraded hot mix asphalt concrete pavements, (1,2,3) and in cold mix or surface treatment applications. (4) Proper processing of steel slag and special qualitycontrol procedures are extremely important in selecting steel slag for use in asphalt paving mixes.
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 .
research on using low CaO unprocessed steel slag as fine aggregate in concrete. Results concluded that the use of the steel slag as fine aggregate had a negative impact on the workability of concrete, but it had positive effect on mechanical properties, and the best
The objective of reseach paper is to study behavior of steel slag concrete. Also to study comparison of compressive strength of steel slag concrete for 0%, 10%, 20%, 30%, and 40% replacement of fine aggregate by steel slag. The concrete specimen cubes are .
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
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 %
partial replacement coarse and fine aggregates with steel slag cing only the coarse aggregate in FA:CA (20:80) mix with the air cooled LD slag in three different proportions such as 10%, 30% and 50% . keeping FA20% constant and replacing coarse aggregate by slag in 80% of CA. b) Replacing only the fine aggregate in FA:CA (20:80) with
