As there were very limited studies on the combination related to the partial replacement of glass powder to cement and steel slag to fine aggregate, an attempt has been made by partially replacing the cement with 20% glass powder and fine aggregates with 25%, 50% and 75% of steel slag in M20 grade SCC.
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 us 7 mixes (M1, M2, M3, M4, M5, M6, M7) totally. After conducting various ...
Due to the differences of density between steel slag and limestone, volume was chosen as an indicator for steel slag replacement. Thus, a volume–mass conversion was performed on aggregates of steel slag and limestone. The composite gradation of "steel slag + limestone" mixture in 0.45 power chart is illustrated in Figure 4.
In addition, steel slag can be used as aggregates in concrete to replace natural aggregates, because it has favorable mechanical properties, including strong bearing and shear strength, good soundness characteristics, and high resistance to abrasion and impact. ... Steel slag aggregates are fairly angular, roughly cubical pieces with a flat or ...
Seven mixes were prepared by partially replacing Steel Slag as fine aggregate and Walnut Shell as coarse aggregate and tested for mechanical properties …
The investigation revealed that there is a increase in compressive strength with increase in percentage of steel slag after 7 days and Results of replacement of coarse aggregate with steel slag ...
The main conclusion has been the suitability of using steel slag as a replacement in the hot asphalt mixture/incorporated RAP aggregate. In particular, Fakhri and Ahmadi [ 26, 29 ] observed that incorporating RAP with steel slag improved the dynamic creep, resilient modulus, fatigue life, and indirect tensile strength of asphalt mixes.
Properties of cement Properties Values Fineness 5% Consistency 29% Initial setting time Specific gravity 45 min 3.15 2.1.2 Aggregates Steel slag, a by-product obtained from the steel manufacturing plant, is crushed into pieces and used as a fine and coarse aggregate along with conventional fine and coarse aggregate.
The replacement of steel slag up to 75% does not have a major impact on the material's strength, while the replacement of RHA has led to a 30% increase in the material's strength. ... Steel slag aggregates are used in cement concrete as a substitute for natural materials is a novel notion. A.A.F. Shaheen [1].(See Fig. 2). Download : …
Steel slag is a sustainable, high-strength alternative to natural aggregates found in traditional cement. ... Replacing natural aggregate thus becomes an alternative solution to tackle sustainability.
This work primarily intends to study the mechanical behaviour of high strength fiber reinforced concrete (HSFRC) of M70 grade such in compression and tension tests, by replacing coarse aggregate by 40 %, 45 % and 50% with steel slag and pondering 1 % of steel fibers. The microstructure of concrete mixes is analysed, results indicated that 50% ...
Replacing natural aggregates by slag created 1.4 to 2.4 times higher tensile strength and up to 1.3 times greater compressive strength (with 15% slag aggregate). The cause of the decline in compressive strength with more than 50% slag aggregate was found to be due to slag´s fineness compared to sand. ... The steel slag aggregate concrete ...
4.6 Steel slag aggregate, SSA. Steel slag aggregate is a by-product of the steel manufacturing process. There are two types: SS produced by basic oxygen furnaces (BOFs) and SS produced by electric arc furnaces (EAFs).
