Raman spectra included in Figure 13

The chemical structure of the healing product analysed using LabRam HR800 Raman spectrometer, for the samples exposed to tap water (TP) and waste water (WW), respectively. The labelling of the samples is as follows: SI_R - represents plain mortar (samples in Set I) SI_R+GM_I_ACG-Ø - represents plain mortar with growth media I (calcium nitrate and yeast extract) and aerated concrete granules SI_R+GM_I_ACG-S - represents plain mortar with growth media I (calcium nitrate and yeast extract) and aerated concrete granules with spores SII_R - represents plain mortar (samples in Set II) SII_R+C_ ACG-Ø - represents plain mortar with calcium nitrate and aerated concrete granules SII_R+YA_ ACG-Ø - represents plain mortar with sodium acetate and aerated concrete granules SII_R+GM_II_ACG-Ø - represents plain mortar with with growth media II (calcium nitrate and sodium acetate) and aerated concrete granules SII_R+GM_II_ACG-S - represents plain mortar with with growth media II (calcium nitrate and sodium acetate) and aerated concrete granules with spores
