| Abstract: | Tests have been carried out with chemicals that give rise to coloured compounds through a selective reaction with certain mineral species present in cement paste. In the case of carbonated concretes (pH≅9), the reaction with potassium ferrocyanate dyes the cement paste a strong blue colour that disappears when the concrete is treated again with a slightly more alkaline solution. Both in carbonated concretes and in young concretes with an alkaline reserve (pH≅12.5), the tannic acid dyes the cement paste dark brown. |
