The flotation behaviors of perovskite, titanaugite, and magnesium aluminate spinel (MA-spinel), using octyl hydroxamic acid (OHA) as the collector, were investigated using microflotation experiments, zeta-potential measurements, Fourier transform infrared (FT-IR) analyses, X-ray photoelectron spectroscopy (XPS) analyses, and flotation experiments on artificially mixed minerals. The microflotati...

The objective of this paper is to investigate the use calcium aluminate cements as alternative within context nuclear waste stabilization by solidification. Using an external 60Co source, effect γ-radiation on H2 gas production one cement-based materials (cement “Ciment Fondu”) and its stable hydrates, was studied. amount produced these cement pastes found be much lower (up five times less) tha...

The objective of this research is to investigate the possible reuse dredged sediments from port Cherbourg, France, as an alternative material in road engineering and a backfill material. These contain high percentages organic matter (OM), presence OM sediment, even small amounts, can affect properties sediments. This was carried out two series: sediment treated with traditional hydraulic binder...

The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...

OBJECTIVE To evaluate the shear bond strength of a novel calcium aluminate-based cement, EndoBinder (EB), to dentine in comparison with Grey and White Mineral Trioxide Aggregate (MTA). MATERIALS AND METHODS Root canal hemi-sections obtained from 30 extracted molar teeth were embedded in self-polymerized acrylic resin and were grounded wet in order to obtain a flat dentine surface. Next, the r...

AIM To evaluate the physical and mechanical properties of two cements with a similar chemical composition to mineral trioxide aggregate and to attempt to improve their properties by producing a composite material. METHODOLOGY Two cement types were used: a mixture of calcium sulpho-aluminate cement and Portland cement (CSA) and calcium fluoro-aluminate cement (CFA) in conjunction with an admix...
