EnglishUsually, green roofs are made with natural materials, as lapillus or pumice rock, which have the same porous characteristic of the granular AAC. To verify if this substitution was a good hypothesis, we have carried out chemical and physical analysis on a mixture of 70% of soil and natural peat and 30% of granular AAC. We compared all the results with natural green roof characteristics, finding a good connection between these two groups of values. In fact the pH value of the water extract is of 7.23; the organic matter is less than 4.08; the apparent density is 459.2 kg/m2; the demand for high water retention capacity is completely satisfied by the value of 222.62% of the mass of water absorbed relative to the mass of the dry sample. For this reason, we think that the introduction of granular waste AAC within the structure of a green roof could help to reduce industrial wastes and respects the European ideas of a sustainable future.
