An experimental investigation on partial replacement ... concrete made with steel slag and steel millscale. This research has shown that replacing some percentage of natural aggregates by steel ... with steel slag and mill scale aggregates. For this research the percentage of the volume of natural aggregates normally used in concrete was partial
Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...

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] investigated the possibility of using a carbonated LF slag as a fine aggregate in concrete. The slag was treated with CO. 2
EXPERIMENTAL INVESTIGATIONS ON PARTIAL REPLACEMENT OF STEEL SLAG AS COARSE ... replacement for both fine and coarse aggregates in a conventional concrete mixture. Steel slag is a byproduct ... * Hardness of dolomite measured on same scale is 3 to 4. ** Typical CBR value for crushed limestone is . Steel Slag Aggregates
10mm length. Experimental investigation was done using M25 mix and tests were carried out as per recommended procedures by relevant codes. The results were compared with conventional concrete it was observed that concrete blocks incorporated with steel powder increased its compressive strength by % and tensile strength by %.
with steel mill scale gave the highest increase in compressive strength. Li Yun feng (2009) found that concrete with good performance can be produced using mineral admixtures consisting of steel slag powder and blast furnace slag. In the present paper an experimental investigation on the mechanical properties of concrete has been made with 0% ...
The experimental results show the application of steel slag sand may reduce the dosage of cement clinker and increase the content of industrial waste product using steel slag sand. Isa Yuksel, Omer Ozkan, Turhan Bilir, 2006 [2] experimented use of non ground granulated blast furnace slag as fine aggregate in concrete.
Section 430Portland Cement Concrete Pavement Page 6 9. Keep reinforcing steel free of dirt oil paint grease mill scale and loose or thick rust that could impair the bond of the steel to the concrete. 10. Arrange operations to prevent leaveouts in continuous reinforced concrete pavement. The .
Fig. 2. Relationship between mill scale weight and consumed electric energy consumed electric energy also increased about 769 and 594 kWh per mill scale ton for type B and C heats, respectively. These increments can be attributed to the melting of mill scale in the furnace and the endothermic behavior of iron oxides reduction process by carbon.
This paper presents result of an experimental investigation carried out to evaluate effects of replacing aggregates (coarse fine) with that of Slag (Crystallized Granular) which is an industrial waste byproduct on concrete strength properties by using Taguchi''s approach of optimization. Whole study was done in three phases, in the first phase natural coarse aggregate was replaced by ...
admixtures with steel slag powder and blast furnace slag powder mixed in concrete. Saud AlOtaibi (2008) studied use of recycling steel mill as fine aggregate in cement mortars. The replacement of 40% steel mill scale with that of fine aggregate increased compressive strength by 40%,
with steel mill scale. And when steel mill scale is replaced with sand the strength of the concrete is increased to times of controlled concrete. (The Strength of Controlled Concrete Cube is 25N/mm2, 25% partially replaced steel mill scale 2concrete attains /mm ) Reference [1], Jithu G Francis, JunaidK T,,
Carlos Thomas, ... Francisco Agrela, in New Trends in Ecoefficient and Recycled Concrete, 2019. Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.
Steel slag has been procured from Jindal Stainless Steel Limited, Hisar, Haryana. Fig. 1 shows the stabilized steel slag used for the study. AOD steel slag chemical composition is shown in Table Portland Cement (OPC) 43 grade complying with IS: 8112 (1989) and having specific gravity of was used. The consistency and fineness of cement used was % and 5 mm respectively.
Oct 24, 2015· Another important objective of this research was to evaluate the radiation shielding properties of heavyweight concretes containing iron ore, steel mill scale, two types of barite, or steel slag as aggregates. The experimental results showed that the attenuation coefficient varied from to 1/cm, while the unit weight of heavyweight ...
