Concrete made with recycled steel slag is 17 percent stronger than traditional concrete. Disposing of slag is a millennia-old problem, but the "waste material" is …
The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition …
Compared with the control limestone aggregate concrete, the concrete made with steel slag had comparable or even higher compressive strength, flexural strength and modulus of elasticity. When ...
The study was conducted to define and analyse the physical, mechanical, and durability properties of eco-friendly concrete made with 50% EAF oxidizing slag aggregate in addition to 30% fly ash (Mix C) compared with conventional concrete mix (Mix A) and concrete with 30% fly ash (Mix B) of two grades M20 and M30.
Slag concretes have been used successfully in concrete for many yeras in many countries throughout the world. There is much evidence, both from laboratory test data and in service records, to suggest that there are potentially many technical benefits to …
This paper presents the results from an experimental testing program conducted to investigate the performance of high strength concrete made with copper slag as a fine aggregate at constant workability. The effect of admixture addition on the properties of concrete mixtures made with different proportions of copper slag is also discussed. 2.
For mix CSSC-1 made with coarse slag aggregate concrete, similar flexural strength was obtained compared with the control mix NC-1; but the flexural strength of mix CSSC-2 was 19−24% lower than that of the control mix NC-2. Adding waste glass in concrete mix SSGC-1 caused a flexural strength loss of 2.3–10% when compared to mix CSSC-1 in ...
This paper aims to investigate the possibility of utilizing steel slags produced in Croatian plants as a concrete aggregate. Aggregate properties were determined on coarse slag fractions (4–8, 8–16 mm) according to the relevant European Standards. Considering the obtained results, slags were specified in accordance with the classes as given in the main …
