Results of a research of the damping properties of cement composites with various water cement relation, with additive super – and hyper softeners, fillers – ground quartz and microsilicon dioxide, quartz sands of various fineness at cyclic influence of negative and positive temperatures are given in the article. The damping properties of cement composites are determined by a resonant method. It is revealed that the studied structures of composites show changes of the damping properties at cyclic influence of negative and positive temperatures. Decrease in the damping properties is characteristic of all structures at the beginning of the researches, and then at increase in cyclic influence of negative and positive temperatures there is a further reduction or increase in an indicator. It is established that increase in decrement of fluctuations with growth of duration of an experiment is caused by de-structive processes in structure of material.

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.
