Abstract
Due to biological colonization, properties of building materials change. Green algae represent one group of the entire complex of biodeteriogens that interact with each other. For the purpose of testing algae growth risk on concrete with varied composition, a growth resistance testing methodology was developed based on ČSN EN 15458 (672032) Paints and varnishes -Laboratory method for testing the efficacy of film preservatives in a coating against algae. The modified method was employed to test ten samples of concrete with different composition, i.e. two types of cement and two types of classical fly ash were incorporated in the samples. The green algae growth was influenced by both the type of cement and the type of fly ash used. The results show that any addition of classic fly ash increases the risk of green algae colonization on the surface of concrete.
