Zaichenko L. Fine-drained cement concretes activated in the rotation electromagnetic field

Object - fine-grained cement concrete mixtures and concretes, containing the ferromagnetic mineral additives activated in the rotation electromagnetic field; purpose - development of fine-grained cement concretes compositions with the promoted physical-mechanical and operating properties which contain ferromagnetic mineral additives on the basis of establishment of mechanism of activating of structure formation processes and properties of concrete in the rotation electromagnetic field; methods - standard and special; the magnetized of saturation of mineral additives is determined by magnetic scales; composition of hydrated products of cement paste - DTG, X-ray, IRS; novelty - conformities to the law of forming of structure and properties of fine-grained cement concretes which contain ferromagnetic mineral additives in the composition are set, under act of the rotation electromagnetic field; results - technological regulation of production of the figured elements of paving (FEM) from a fine-grained cement concrete containing ferromagnetic mineral additives is developed and inculcated; the sphere of the use - production of concrete and reinforced concrete products.
