MINERAL PARTICLES COATED WITH A CROSS-LINKED POLYMER AND METHOD FOR PREPARING SAID PARTICLES

摘要

The invention concerns mineral particles coated at least partially with a cross-linked polymer coat. The invention also concerns a method for treating mineral particles in whereby the particles to be treated are fluidized in a gas flux, and simultaneously, the particles are sprayed with a solution of at least one polymer, at least a cross-linking agent of said polymer. Finally, the invention concerns the use of said particles in cementitious media.
