The studies on identification of density variations of atmospheric particles including [PM.sub.2.5] and their impacts show that the hygrometric characteristics of different emission particles vary significantly under different atmospheric condensation conditions.
In some cases, the parchment surface was treated with egg white, fats, vegetal oils, tannin, and alum to obtain more stability of the support to the hygrometric variations and it was subjected to a smoothing process with pumice [1].
This type of traditional greenhouses answered fairly well in the countries of the Mediterranean basin, is confronted to the intense nocturnal cooling, which sometimes results in the reversal of the internal temperatures and complications of overheating and hygrometric variations According to the seasons.
Thus, a hygrometric diagram shows that the air contains a larger quantity of water vapours when it's hot than when it's cold.
Various research papers have shown that hygrometric shrinkage and its associated cracking of earth-based materials can be greatly reduced by introducing fibres into the mixture and this study confirmed these findings by demonstrating that shrinkage due to the drying process was significantly reduced with the inclusion of natural fibres into the soil mix.
