Carbonation

investigated here but are also supposed to be of importance in the colonisation process. A high pH, in particular, is known to delay micro-organisms colonisation, as can be observed on freshly applied mortars, the colonisation being possible once the carbonation process has lowered the alkalinity [15]. Conclusions These accelerated experiments using the water-streaming test confirmed the effect of the underlying material characteristics on algae and cyanobacteria settlement, roughness and porosity showing

ride the boom of “green technologies”. This transition to new energies will not be painless with the possible intersection, in the next 10 to 20 years, of other crises such as a drop in the world’s crude oil production. It is clear that the de-carbonation of economies will endure deep changes in the production and consumption of energy. Remember, in fact, that to reduce carbon dioxide emissions by 50% between 1990 and 2010 (notwithstanding Kyoto) will take twenty years to stabilize emissions and
