Abstract
In a modern civil engineering, it is important to erection construction in extremely complicated and difficult
environmental conditions. Additives and admixes to concrete enable to achieved higher mechanical properties
of concrete mixtures. This operation causes, the constructions accomplish durability in various environmental conditions. In the article, authors described scientific research made on concrete with additives: latex based polymer and
microspheres. The tested additives were used in to different proportion each and they were combined with each other.
The aim of research was to determine influence this two additives on compressive strength after 28 days, after 90
days, a tensile splitting strength, a sorptivity, a freeze-thaw resistance and a compressive strength on the specimens
after freeze-thaw resistance test. Received results clearly show decrease in compressive strength of the modified concrete mixtures. The specimens prepared without additives achieved the highest compressive strength results.The researchers observed also increasing liquidity of concrete mixtures and decreasing sorptivity of hardener
concrete under the influence of latex based polymer. The knowledge of basic properties of microspheres from
co-combustion of coal is fundamental to its effect usage of building industry.
