In an incubation study, by adding to the soil converter slag (from Isfahan steel factory, Isfahan, Iran), containing about 24% of Fe oxides, along with elemental sulphur and organic matter, the soil pH has increased, due to the alkaline pH of slag. 95 . generally decreased, while specific gravity of soil " steel slag mixtures increased with higher steel slag content; MDD and OMC increased and decreased, respectively, with higher steel slag content. Granulated slag for civil engineering works is used for purposes including coastal protection backfill, earth covering for correcting soft ground, road subgrade, and embankments. Enter the email address you signed up with and we'll email you a reset link. Steel LD slag has been used as a liming agent for pasture in Northern Spain. Slag-based silicate fertilizer has been widely used to improve soil silicon- availability and crop productivity. properties of steel slag. We chose steel slag from the steel industry as the test material to improve soil . But during the incubation time the pH decreased. Steelmaking slag has several applications. The permeability coefficient can reach the order of magnitude more than 10 −5 when more than 70% of steel slag was added to silt soil. This paper presents the stabilization of expansive soil (C) with steel slag (SS), rice husk ash (RHA), and quick lime (L). Its pH-raising effect is similar to that of ground limestone.

Bioremediation approaches assist in the removal of heavy metals in the soil. The optimum mix is found to be in the proportion of 65 C + 20 SS + 5 L + 10 RHA. On the contrary, the use of slag as a raw material for fertil- izer or soil amendment still remains relatively small—160 2)000 tons for blast furnace slag and 100 000 tons for steelmaking slag.

(PDF) Soil Modification by the Application of Steel Slag | Isaac Akinwumi - Academia.edu This paper provides experimental insights on the modification of a soil using electric arc furnace (EAF) steel slag, which is limitedly used as a construction material because of its volumetric instability. Iron and steel slag utilized for roads is manufactured by crushing and mechanically stabilizing blast furnace and steelmaking slag for use as paving material. It is made by the separation of the molten steel from impurities while the steel is melted in a large furnace. Owing to its high Si content, the use of slag as silicate fertilizer is gaining demand. Slags are the final solid wastes from the steel industry. Various models have been proposed to model aqueous carbonation of steel slag. Direct aqueous carbonation is one of the routes to slag carbonation. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. PLoS One 11, 1–15.
