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 due to their mechanical strength, stiffness, porosity, wear resistance
on the replacement of natural sand with manufactured sand by 0%, 25%, 50%, 75%, and on concrete properties. The steel slag is one of the alternative materials that can be used instead of cement as a partial replacement in concrete by 0%. %, 5%, %, 10%, %, 15%. The results are being calculated by testing the cubes, cylinder and prism.
Influence of Copper Slag in Concrete as Partial Replacement for Fine Aggregate N. Vinoth Kumar1 S. K. Divya2 A. Sattainathan Sharma3 1,2,3Assistant Professor 1,2,3Department of Civil Engineering 1,2,3Valliammai Engineering College, Kancheepuram, India Abstract—Concrete is the widely used construction material.
of steel slag as partial replacement of coarse aggregate in concrete is economical for the better strength and workability it imparts up to 75% replacement level. It is found that increase in replacement level of steel slag above 75% decreases the strength and workability of concrete.
Slag replacement can assist in reducing high hydration temperatures, which is a problem in concrete with high cement contents. Slag replacement levels were studied of 70%, 50%, 30% and 0%. Slag replacement levels studied were of 70%, 50%, 30% and 0%.
the possibility of utilizing granulated blast furnace slag(GBS) in bendable concrete as a substitute for partial fine aggregate to reduce the environmental problems relating to fine aggregate mining and waste disposal of slag. The use of GBS will also make the bendable concrete more .
percentage steel slag and quarry dust to be replaced is found out by conducting 7days and 28 days compressive strength on cubes of size 150 mm x150mmx150mm with 20%, 40%, 60%, 80% and replacement of coarse aggregate by steel slag and fine aggregate by quarry dust. To study the strength loss, weight loss characteristics of concrete.
concrete dissertation work deals with the study of partial replacement of natural fine aggregate by steel slag and natural coarse aggregate by waste limestone aggregate in m20 grade of cement slag is a waste byproduct obtained from the iron and steel plants and.
similar to the fine aggregate, so it can be used as a replacement for fine aggregate in concrete. By the replacement of 1%, 2% and 3% of steel slag (byweight) as a replacement for fine aggregate will produce a concrete with durability requirements. This work shows the results of an experimental study on various strength parameters of concrete ...
Influence of Copper Slag in Concrete as Partial Replacement for Fine Aggregate N. Vinoth Kumar1 S. K. Divya2 A. Sattainathan Sharma3 1,2,3Assistant Professor 1,2,3Department of Civil Engineering 1,2,3Valliammai Engineering College, Kancheepuram, India Abstract—Concrete is the widely used construction material. In which fine aggregate is one of the important constituents.
Steel slag has higher strength characteristics than normal aggregate, which result in more strength differences between slag aggregate concrete and natural aggregate concrete. If the replacement of steel slag increases beyond 75%, to maintain the workability of concrete certain water reducing admixtures should be added. Four mixes were prepared by partially replacing steel slag as fine aggregate and .
Steel slag is such materials which could be used as a partial replacement for fine aggregate [2]. Induction furnace steel slag is a byproduct of steel manufacturing industry, which is .
In this study we are focusing on the use of selected waste of steel industry (steel slag) as a partial replacement for fine aggregate in the production of concrete. In this research study, concretes were made with steel slag as substitution for raw fine aggregate.
Owing to the scarcity and harmful of cement for the preparation of mortar and concrete, partial replacement of steel Slag with Msand have been attempted. The effects of replacing cement by steel slag on the compression strength of cubes, split tensile strength of cylinders and textural strength of beams are evaluated in this study. steel slag is obtained as waste product from the sterlite industries.
blast furnace slag (GGBS), glass cullet, etc., in civil constructions. The potential applications of industry byproducts in concrete are as partial aggregate replacement or as partial cement replacement, depending on their chemical concrete comes from the environmental constraints in the .
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.
UTILIZATION OF COPPER SLAG AS A PARTIAL REPLACEMENT . slag as a replacement of fine aggregate on the strength properties. In this report, M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 40%, 80% and in. Read More
After completion of this project it is concluded that, 0% GGBS Replacement with cement and 10%, 20%, 30% 40% Replacement steel slag with sand, It was found to be compressive strength of concrete ...
The target compressive strength for the control specimen is chosen as 58 MPa. While fly ash and copper slag are used for partial replacement of cement and fine aggregate, respectively, defined quantity of silica fume, steel fibres, and polypropylene fibres is added to the mix proportions considered for the study.
The primary objective of the project is to increase the strength of the concrete by replacing coarse aggregate by steel slag and also 30% replacement of eco sand as fine aggregate. As of from literature steel slag is replaced for 0,15,30,45,60,75,90 % which indeed gives .
