SYNOPSIS The properties and deterioration in strength of cemented tailings backfill (CTB )in the underground acidic environment under oxidizing conditions were studied. X-ray diffraction analysis scanning electron microscopy surface CTB was carried out, sulphuric acid corrosion mechanism elucidated. tested included compressive strength, elastic modulus, cohesion, internal friction angle, variat...

Cationic polymers obtained via partial reduction of poly(2-ethy-2-oxazoline)s were studied on their cytocompatibility and buffer capacity in acidic environment.
