Intervención (Méx. DF) [online]. 2022, vol.13, n.25, pp.161-199.  Epub 13-Fev-2023. ISSN 2007-249X.  https://doi.org/10.30763/intervencion.264.v1n25.43.2022.

This research article exposes a possible application of the nopal gum (Opuntia ficus) variety as an additive to promote the durability of adobes, which may be used in the conservation of architectural heritage. This research was carried out in the Laboratory on Cubic Soil Specimens. While preparing the mixtures, different concentrations of previously dehydrated and powdered nopal gum were added. Through moisture retention, capillarity and compressive strength analysis, the samples were evaluated, and the results found-also discussed here-show that adding nopal gum increases the compression strength of soil specimens and reduces capillarity. In fact, it was possible to maintain the cohesion of the particles in the soil samples during their exposure to humid environments. Having obtained such aptitude in the properties of said specimens makes this substance viable for its use in the conservation of adobe buildings.

Palavras-chave : nopal gum; soil; capillarity; compression strength; cohesiveness.
