“…The effect should be considered in both technical and ecological aspects. These aspects should be analyzed in relation to the designing, building and service life of constructions (Vičan, Śpiewak, Odrobinak, & Ulewicz, 2017;Tsapko, 2018).…”

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.
