In this research the questions of microsilica usage and ways of its activation for modification of structure of cement stone and cement on its basis. The actual questions corresponding any type of filler, particularly microsilica are: how and how much should be put, which mechanisms are involving to process of structuring, how much is received result of structure modification and others. Therefore the role of microdispersed fillers in modification process of cement rock and cement on its basis must be viewed in connection with other dimensional inclusions on different large-scale levels. Reducing of concrete consumption by its substitution by microsilica, has a positive influence to physico-chemical characteristics of concrete.

Calculation of the carbon footprint of cement concrete is a complex process including consideration of the phase of primary life (components and concrete production processes, transportation, construction works, maintenance of concrete structures) and secondary life, including demolition and recycling. Taking into consideration the effect of concrete carbonation can lead to a reduction in the calculated carbon footprint of concrete. In this paper, an example of CO2 balance for small bridge elements made of Portland cement reinforced concrete was done. The results include the effect of carbonation of concrete in a structure and of concrete rubble after demolition. It was shown that important impact of carbonation on the balance is possible only when rubble carbonation is possible. It was related to the fact that only the sequestration potential in the secondary phase of concrete life has significant value.
