“…Demand for this sector in the developing world conditions is increasing rapidly, which causes the production capacity to increase. 1,2 This increase in the iron and steel industry is seen significantly in Turkey. The iron and steel industry have been a high production capacity amongst the other Turkey's manufacturing industries.…”

The scale is a waste coming from the metal casting industry. It is an iron oxide layer formed as a result of oxidation after annealing on steel surfaces. Casting wastes, which have been left uncontrolled for many years, have caused considerable environmental damage. In the present paper, the mechanical properties and microstructural characterization of cement mortars, prepared by using scale coming from Turkey steel manufacturer were experimentally investigated. The steel scale was used as a partial replacement of cement. Recycling of solid waste scale is considered as an environmental-friendly alternative to solve the problem of disposing of wastes. Cement mortar admixtures were prepared by variable percentages of scale from 2% to 10%. How to cite this article: Mutuk T, Demirbaş AK, Çevik S, Mesci Oktay B.

Promoting the effect of zinc‐rich epoxy via poly(aniline‐co‐anisidine)/iron waste composite on corrosion protection of steel

The purpose of this article was to evaluate the performance of a poly(aniline‐co‐anisidine)/iron waste composite (COIW) as an anticorrosive pigment for primer coatings. A procedure was outlined to prepare COIW and evaluate its anticorrosive properties following the electrochemical behavior and corrosion test of the coated steel. Various zinc‐rich epoxy primers were formulated by replacing part of the zinc powder (ZP) pigment with COIW. In all formulas, the ratio of pigment to epoxy resin was fixed at 2. In the pigment mix, the percentage of COIW was ranged from 5% to 60% by weight to the ZP. The performance of the formulated primers was estimated by the salt immersion test and potentiodynamic polarization measurement (corrosion potential, polarization resistance, and corrosion rate essays). It was demonstrated that COIW is effective in protecting steel from corrosion when it is used in combination with ZP.

“…During the steelmaking at both routes and also at the reefing step, the main residues generated can be divided into categories such as slag, sludge, and dust [2]. The mineralogical and chemical compositions of each of these wastes vary according to the raw materials employed in the process and to what they have as common elements, mostly composed of iron, carbon, calcium, magnesium, silicon, and manganese and still containing smaller proportions of aluminum, zinc, alkaline earth metals, and traces of other elements [3].…”

The steelmaking industrial sector generates a wide variety of solid wastes, predominantly composed of slag, dust, sludge, and scrap. The need to find a correct environmental alternative to recycle steelmaking wastes, as well as the possibility to bring some technical advantageous to clay bricks for civil construction, makes this industrial segment present itself as an excellent alternative for the reuse of these residues. In this way, some studies were presented in this chapter that evaluated the effect of incorporation of different steelmaking plant wastes such as blast furnace sludge, sludge, and slag from oxygen steel-refining process in the physical and mechanical properties of clay bricks for civil construction. As final considerations, the most investigated wastes present a particle size distribution compatible to clay brick processing. Although the wastes display different chemical and mineralogical composition, low amounts are well tolerated by the ceramic, not impairing the physical and mechanical properties. Furthermore, the presence of determined constituent, as, for example, fine coke in blast furnace sludge, can contribute significantly to save energy during the firing stage.
