Abstract: results of a research of the damping properties of cement aggregates with different water cement relation, with the component super – and hyper plasticisers, fillers – ground quartz and microsilicon dioxide, quartz sands of different fineness in case of cyclic influence of the increased humidity and the variable increased temperatures are given in the article. The damping properties of cement aggregates are determined by a resonant method. Keeping of samples in the conditions of raised temperatures and humidity significantly influences the decrement of oscillations practically of all compositions. It is set that the damping properties of cement aggregates are defined by the damping properties of a cement stone; introduction to composition of the cement test super – and hyper plasticisers leads to lowering of this index; adding in composition of the cement test of powders of microquartz and microsilicon dioxide causes essential increase the damping properties of a cement stone with super – and hyper plasticiser.
Keywords: the cement aggregates, filler, concrete of new generation, thermocyclic tests, damping properties, the logarithmic decrement of oscillations
