 — A series of tests were performed to assess the influence of copper slag fine aggregates (CUS) on the corrosion behavior of horizontal steel bars in reinforced …

 — Concrete made with w / c 0.55 possess high flowability (100–175 mm) to have a maximum slump value of 175 mm, and therefore higher workable concrete. …

 — Later in the chapter corrosion of carbon steel weldments that are more often called preferential weldment corrosion would be discussed. The primary reasons for this type of corrosion are carefully elaborated on whether it's induced by galvanic corrosion or it's related to the composition and microstructure differences associated with the heat …

of the concrete with copper slag is lower than the control (no copper slag) mixes [1726–, 2031, ]. Very few papers assessed workability of the copper-slag concrete. Gener-ally it was found that copper slag may increase workabil-ity of concrete mixes (e.g. [1731–]) but most of these 20, papers used superplasticizers to enhance workability of

 — The rotating method is carried out to investigate the effects of La 2 O 3 content (0–4 wt%) on the viscosity of copper smelting slag at high temperatures, the apparent activation energy is evaluated according to the Arrhenius equation and the structural characterization of this quenched slag is characterized by Raman …

 — As a result, an effort is made to partially replace fine aggregate in the construction industry with copper slag. The current paper examines the laboratory testing of various concrete mixes (Mix 20, Mix 40, and Mix 60) containing copper slag waste as a partial replacement for fine aggregate (0% to ). The fresh properties and …

 — Waste recycling and reuse is an important component of sustainability. Extensive research is being conducted to address this issue by incorporating industrial by-product such as steel slag, copper slag, fly ash, ferro-chrome slag, and so on into the construction industry. Steel slag, which is mostly calcium carbonate, is created as a by …

 — The slag in pyrometallurgical operations plays a major role affecting the life of furnace refractory. As such, comprehensive mineralogical and chemical slag examination, physical property determination including the slag melting point or liquidus, and viscosity are necessary for precise understanding of a slag.
