Quality Concrete–Concrete Practices. The first defense against corrosion of steel in concrete is quality concrete and sufficient concrete cover over the reinforcing bars. Quality concrete has a watertocementitious material ratio (w/c) that is low enough to slow down the penetration of chloride salts and the development of carbonation.
An interesting paper by Bakharev et al. (2000) tried to rationalize the study of workability of concrete that incorporated alkaliactivated slag as the only binder. The activators were liquid sodium silicates (4 ± 7% Na, mass of slag) and a multicompound activator (NaOH + Na 2 CO 3) (8% Na, mass of slag).To ameliorate the workability, measured by the slump loss test, different additives have ...

The primary focus of the current work is the study of how cement extenders impact on the corrosion characteristics of embedded steel in concrete. The investigation was limited to those materials commonly used in South Africa (slag, fly ash,and condensed silica fume) and performed under laboratory conditions at 30°C.

In the last decades, the use of steel fibers as concrete reinforcement has been shown to be useful in several special applications (Mohod et al. 2012, Afroughsabet et al. 2016. This was also the ...
The influence of steel slag expansion level on the early stage performance of hot mix asphalt (HMA) is evaluated. Initially, samples of LinzDonawitz type steel slag with different levels of expansion (%, %, %) were submitted to physical, mechanical, and morphological characterization to assess the effects of expansion on individual material properties.
Slag aggregates are an unavoidable byproduct of the steel and iron industry which can be used as an alternative. Hence, an attempt is made in this study to replace conventional concrete with the development of innovative green SCC by partial replacement of ingredients of conventional concrete like cement, fine aggregates and coarse aggregates ...

Geomaterials can be often classified into two groups: geomaterials such as soil and rock, and byproduct materials such as mine tailings, coal fly/bottom ash, foundry sand, kiln dust, blast furnace/steel slag, reclaimed concrete and asphalt. Studies on these materials and their mixtures have been carried out extensively for geoengineering applications, including the .
