Effects of Mixing Granular Iron with Sand on the Kinetics of

Cutting the iron with sand can reduce costs, but several performance issues arise. In particular, reaction rates are expected to decline as the percentage of iron in the blend is diminished. This might occur simply as a function of iron content, or mass transfer effects may play a role in a much less predictable fashion.

To solve this problem, this paper proposes an original mortar replacement (M) method to reuse waste solids and reduce cement consumption. In the experiment, the author employed an M method which replaces water, cement, and sand with WITP under constant water/cement and found that the strength development can be significantly improved.

11.11.2022Since clay and sand are present in WAS, thermal processing of these wastes results in the partial reduction of SiO 2 to Si. At low temperatures (500–700 C) and a short time (30 min) treatment of 50 wt.% Fe 2 O 3 + 50 wt.% WAS mixtures an active reduction process can be observed (see Fig. 1 a). Hematite is reduced to magnetite (Fe 3 O 4 ).

Mathematical Analysis of the Effect of Iron and Silica on the Reduction

The reduction index (RI) is classified into RIT (reduction index of total Fe-Mn oxides), RIM (reduction index of only manganese oxide), and RIF (reduction index of only iron oxide). The softening-melting property (SMP) is classified into (start of softening), (end of softening), (start of melting), and (end of melting).

Iron-coated sand (ICS) is a residual product from drinking water production. ICS has a high phosphate adsorption capacity and can be placed around tile drains taking no extra space which increases the farmers' acceptance. The main concern regarding the use of ICS filters below groundwater level is that limited oxygen supply and high organic matter concentrations may
