Despite some popular misconceptions, titanium is not a rare or an exotic element; in fact, it is the ninth most abundant element on earth's crust, with an average abundance estimated between 0.3% and 0.9% wt. [1], [2].Because of its strong affinity with oxygen, titanium's most common minerals are oxides [3].These minerals (Fig. 3.1) …
Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace. This paper reviews the production, processing, and characteristics of steel slag, and its ...
Annually more than 400 Mt of metallurgical slags are produced worldwide [1,2,3,4,5].From the annual Cu concentrate smelter production capacity, which is equal to around 21 Mt of copper metal in 2021, it can be estimated that more than 45 Mt of CUS were produced from primary sources assuming a slag to copper ratio of 2.2 [3, 4].Only …
Slag cement has good water retention, good plasticity, less bleeding, and good workability. It can inhibit the dissolution of heavy metals such as high-valent chromium in concrete. Reducing the heat of hydration is beneficial to prevent cracks caused by the internal temperature rise of mass concrete.
