Abstract

Castable and curable cement-based powder compositions comprising: i) particles of a magnetic or magnetizable particulate material, and ii) a subcomposition including: cement particles, ultrafine particles of an inorganic material, said ultrafine particles having an average particle size in the range of 0.002-2 mu m, and a surface-active dispersing agent in an amount of 0.1-4 % by weight dispersing agent based on the total weight of said cement particles and said ultrafine particles, said ultrafine particles constituting 3-30 % by volume of said powder composition, said cement particles constituting 2-70 % by volume of said powder composition, said particles of said magnetic or magnetizable particulate material constituting 10-95 % by volume, preferably 30-95 % by volume of said powder composition, and said particles of said subcomposition having an average particle size of at the most 10 mu m; cement-bound bodies having magnetic or magnetizable properties produced from such compositions, and methods of producing such bodies.
