Abstract: Results of experimental researches of an exploitations ability in the conditions of a short-term and long loading of concrete with composite cement type CEM V/B modified in high-voltage electric field are resulted. It is established, that finegrained concrete mixes with composite cements type CEM V/B activated in high-voltage electric field at corresponding modes, are characterized smaller on 23–27 % by indicators of effective viscosity in comparison with similar structures of concrete mixes that provides reduction of a water demand of concrete mixes by 5–7 % at achievement of necessary indicators of slump. It promotes formation of more dense structure of concrete (increase of average density, decrease in average radius of pores and increase of their uniformity on the sizes α). In turn, more dense structure on the modified composite cement causes its increase deformation and performance properties.
Keywords: composite cement, modified, deformations of creep and shrinkage, frost resistance.
