Algae of the Pleurococcus , Trentepohlia and Stichococcus genera were selected for the experiment on the cement composites with total replacement of natural aggregates by recycled photovoltaic glass. The growth of the algae was monitored on cement beams with dimension 40 x 40 x 8 mm (length x width x height) and on the cement crumbling in various proportion. In the case of cement composites with recycled glass from photovoltaic panels, intensive growth was observed in the Trentepohlia genus from the Chlorophyceae class, while in the case of cement crumbling with recycled photovoltaic glass, the most obvious growth in biomass was recorded in the Pleurococcus genus; the Stichococcus and Trentepohlia genera showed minimal or zero growth. This minimal growth is mainly influenced by the pH value and the fact that biocorrosion is accompanied by the effect of symbiotizing microbiota, which mutually support each other, not just one species.
