With the obtained information regarding the different petrographical and petrophysical characteristics of the studied volcanic tuff rocks it is possible to deduce which of these characteristics play an important role in the resistance or the susceptibility of the rock against the weathering. Additionally it is also possible to reconstruct the different climatic conditions applied on a particular tuff rock type and reproduce the decay of that in the rocks in the short- medium- and long-term.Experimental and systematical expansion and swelling pressure measurement under contrasting moisture conditions will allow us to deduce which tuff is more susceptible to decay under particular expansion and swellings pressure conditions.If the main causes of deterioration are known, it is possible to anticipate and predict what kind of rock is more susceptible to decay and therefore take the necessary measures for their maintenance and conservation.If the damage of the building stone in the construction is large and they need to be restored, it will be possible to take the necessary measures to reduce the expansion and swelling pressure and, if it is necessary to replace material, it will be possible to consult a catalog of different rocks that could be favorable according to their characteristics for replacement without altering or changing the historical value of heritage in Mexico.

借助有关研究的火山凝灰岩岩石的不同岩石学和岩石物理特性的信息，可以推断出哪些特性在岩石抵抗风化的电阻或敏感性中起重要作用。另外，还可以重建在特定的凝灰岩类型上应用的不同气候条件，并在短岩石中重现岩石中的衰减。哪种岩石更容易衰减，因此采取必要的维护和保护措施。如果建筑物中建筑石的损害很大，需要恢复它们，则可以采取必要的措施来减少扩张和膨胀压力，并且可以替换材料的不需要材料，可以替换材料，以替代材料，可以替换远处的特征，以征求不同的特征，以征求不同的岩石的特征。 墨西哥。
