ABSTRACT
This paper presents the effects of addition of microsilica additives as well as frost resistance aeration and the characteristics of the studied concrete pores. The study was carried out for 150 frost cycles, freezing and thawing. The pore structure of concrete test was carried out using a device for automatic image analysis and utilization of the Lucia Concrete computer program. The set included: the total air content in hardened concrete, the pore distribution of the L , the contents of micropores A300, and a graph of the distribution of air pores. Furthermore, the following designations were made: the consistency and air content of the concrete mix, water absorption, resistance to compression.
