Content of elements in the surface layer of M 600 concrete. A: without treatment; B: surface which was completely immersed in the culture medium during 28days of P. brevicompactum P4 growth; C: concrete surface which was contacted with air in container during 28days of P4 growth. Each column represents mean measurement of three points located on the concrete surface shown in Figures 2(a)–2(c). Significant differences from option A (p <0.05) are indicated by .
