Eaf Slag As Coarse Aggregate

01-10-2015· A relevant improvement in the compressive and tensile strength, and in elastic modulus, is obtained when EAF slag replaces the coarse natural aggregates. The most relevant compressive strength increase has been observed in Mix E1, which has the same mixture proportion than the control concrete.

01-03-2016· Electric arc furnace (EAF) slag is a by-product of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cement-based materials, due to its good physical, chemical and mineralogical properties. Particularly the re-use as coarse aggregate for concrete

02-09-2015· EAF oxidizing slag as a by-product obtained during the process in steel making industry provides great opportunity to utilize it as an alternative to normally available coarse aggregates. The primary aim of this research was to evaluate the physical, mechanical, and durability properties of concrete made with EAF oxidizing slag in addition to supplementary

The concrete mixtures herein considered were designed with 30% by weight of EAF steel slag as coarse aggregate (d ≥ 5 mm) in order to evaluate the concrete performance behavior with a partial substitution of natural aggregates. In particular, the steel slag had a

This study investigates the effect of delay in compaction on the optimum moisture content and the mechanical propertie s (i.e., compressive strength, ultrasonic pulse velocity, splitting tensile strength, and modulus of elasticity) of roller-compacted concrete pavement (RCCP) made of electric arc furnace (EAF) slag aggregate. EAF slag with size in the range of 4.75–19 mm

According to [13], coarse aggregate fraction is that material retained on 4.75 mm (No 4) sieve, while the fine aggregates fraction is that passing the same sieve. In furtherance, this present study is focused on the evaluation of the influence of steel slag aggregate sizes on the workability and durability of concrete.

EAF (Electric Arc Furnace) slag aggregate was used replacing 30% of crushed lime stone aggregate and it is found that the compressive strength increased in all ages [12]. According to [13], slag as coarse aggregate in normal strength concrete increases workability, compressive,,

The concrete mixtures herein considered were designed with 30% by weight of EAF steel slag as coarse aggregate (d ≥ 5 mm) in order to evaluate the concrete performance behavior with a partial substitution of natural aggregates. In particular, the steel slag had a

They concluded that mixtures containing coarse steel slag aggregate performed better than reference mixtures in terms of marshal stability, flow, permanent deformation and indirect tensile strength, and the mixtures containing fine steel slag aggregate were worse. Additionally, Ameri

According to [13], coarse aggregate fraction is that material retained on 4.75 mm (No 4) sieve, while the fine aggregates fraction is that passing the same sieve.

slag with natural aggregate is shown in Table 2. Test results have shown that, EAF steel slag is preferred in high stressed areas where conventional materials have failed (Kehagia, 2008). This is largely due to its advantageous technical properties which facilitates use not only for unbound layers like road bases and sub-bases, but also for surface

the natural aggregates with EAF slag and BFD powder, as coarse aggregate and fine aggregate respectively, complying with technical and environmental requirements. The total substitution with EAF is considered taking into account that in Colombia this material is waste, since it has no use and is

but since some investigation [11] revealed that EAF slag, as fine aggregates in the ordi-nary concrete, caused pop-out in concrete walls, the more appropriate use of EAF slag seems to be in substitution to medium or coarse aggregates. In this sense, there are some works which are referred to the use of EAF slag in ordinary concretes [12, 13].
