Anosovite (Mg0.3Ti2.7O5) phase was successfully separated from synthesized titanium bearing blast furnace slag by super gravity. Supposing that the titanium exists in the slag in terms of TiO2, the mass fraction of TiO2 is 23.49% in the parallel sample without centrifugal separation. With the parameter of t=5min, T=1553K and the gravity coefficient ranged from 600 to 1000, the mass fraction of TiO2 in the concentrate increase from 40.17% to 58.35%, while the recovery ratio of Ti in the concentrate slightly decrease from 83.49% to 81.81%.

The structure of a quenched blast furnace slag containing 5 mass% TiO2 was investigated via molecular dynamics simulation and Fourier transform infrared spectroscopy. The simulation and experimental results obtained revealed that the slag possesses a depolymerized network of [SiO4] and [AlO4] tetrahedra. At a fixed CaO/SiO2 mass fraction of 1.17 and 12 mass% Al2O3, increasing the amount of MgO decreased the bridging oxygen fraction in the slag system, thus resulting in silicate depolymerization. At a fixed CaO/SiO2 mass fraction of 1.17 and 8 mass% MgO, increasing Al2O3 content increased the bridging oxygen fraction because of the polymerization of aluminate structures. At a fixed 8 mass% MgO and 12 mass% Al2O3, increasing the CaO/SiO2 mass fraction from 1.07 to 1.50 decreased the bridging oxygen fraction because of the depolymerization of silicate and aluminate structures. Analyzing the slag structure via FT-IR spectroscopy verified these behaviors.

In the article studies of oil-filled compositions with the addition of blast-furnace slag for strength at elevated temperatures are presented. The rheological parameters of the slag cement slag cement mortar, as well as the setting time, were studied. Conclusions are drawn about the prospects of further study of slag cementcontaining compositions.
