Homogenization of the nanomodified concrete mixture in the magneto fluidized layer

Abstract

Recently, nanotechnologies are beginning to be widely used in construction, which are aimed primarily at improving the quality of mineral binders and, above all, Portland cement. Two directions are observed: the first involves grinding the cement particles before using it, and the second consists in adding nanodispersed materials to the cement as modifiers. The magneto fluidized layer is a suspension of needle-shaped ferromagnetic elements in a rotating electromagnetic field. Ferromagnetic elements in the magneto fluidized layer perform intensive rotational and translational movements, colliding with each other and with the walls of the apparatus. As a result of intensive movement and impact between ferromagnetic elements Portland cement particles are crushed, and nanomaterial particles are evenly distributed in the volume of the entire concrete mixture.
