From Fig. 4 it can be suggested that up to 20% natural coarse aggregate can be replaced with steel slag aggregate in pavement concrete. Increase in percentage of steel slag aggregate beyond this has shown a reduction in strength characteristics in comparison with conventional concrete. IV. .
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 %
of 60%,70% and 80% of coarse aggregates by steel slag which is produced as a waste material in steel industry and has a negative impact on environment when disposed. The investigation reveals that the steel slag could be utilized as coarse aggregate in all the concrete applications and shows a
KeywordsSteel Slag aggregate, coarse aggregate, alternative material for concrete, Compressive strength, Flexural Strength. I. INTRODUCTION Blast furnace slag is produced as a byproduct during the manufacture of iron and steel. Significant quantities of steel slag .
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
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.
steel slag as an alternative material for aggregate in concrete. This work is a study of physical properties and strength behaviour of concrete by partially replacing cement with Calcium Bentonite powder and fine aggregate with steel slag. Concrete specimens prepared by partially replacing cement with different percentage of Calcium
Granular material such as sand, gravel, crushed gravel, crushed stone, slag, and cinders. Aggregate is used in construction for the manufacturing of concrete, mortar, grout, asphaltic concrete, and roofing shingles. It is also used in leaching fields, drainage systems, roof ballast, landscaping, and as a base course for pavement and grade slabs.

the steel slag coarse aggregate is significantly stable in the magnesium sulphate and superior to that of the basalt aggregate. In general, the steel slag aggregate has properties which are comparable to the basalt aggregate. So, it is obviously potential to utilize the steel slag as coarse aggregate in the concrete.
Abstract. This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous paving mixtures. The coarse and fine aggregates shall consist of hard, tough, durable pieces of steel slag, and shall be processed, as necessary, by crushing or screening, or both, and magnetic separation for the removal of metallics.
the partial replacement of coarse aggregate by Steel Slag in concrete. The properties of Steel slag and conventional materials were studied. The work was conducted on M30 grade mix designed by IS and IS . The replacement of coarse aggregate by steel slag in the range of
Concrete In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense readymixed concrete. Blast furnace slag can also be used to make Ground Granulated Blastfurnace Slag (GGBS) which is used as a cement replacement in concrete.
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 physical and chemical properties of ACBFS are presented, as are the properties of the concrete produced with ACBFS coarse aggregate.
concrete as coarse aggregate was carried out for the sustainable use of construction materials in Bangladesh [Mohammed et al 2015]. Investigations on other possible alternatives, such as steel slag may be conducted. The demand of steel in Bangladesh is estimated at about 3 million metric ton with % growth in each year.
strength of Blast Furnace Slag aggregate concrete is found to be higher than that of conventional concrete at the age of 90 days. It has also reduced water absorption and porosity beyond 28 days in comparison to that of conventional concrete with stone chips used as coarse aggregate.
for the represent of 15% GGBS and 30% steel slag. Key Words: Steel slag, GGBS Concrete aggregates, OPC, Compressive strength, 1. INTRODUCTION Concrete plays a critical role in the design construction of the nation''s infrastructure. Almost three quarters of the volume of concrete is composed of aggregates. To meet the

% 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
PDF | This 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 ...
The diameters of coarse quartz sand, medium quartz sand, and fine quartz sand ranged from to mm, to mm, and to mm, respectively. The steel slag aggregate diameter range was the same as that of coarse quartz sand. Figure 3 shows the photo of the steel slag aggregate and coarse quartz sand.
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 %
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
Mar 15, 2014· The use of RCA and steel slag as coarse aggregate in normal concrete mixes is useful in reducing the environmental problems created by dumping these materials, and also helps to maintain sustainability of the environment by reducing the new quarries needed for new concrete. 2.
