|Abstract: ||After many years of war, great efforts have been made for the socio-economic development of Angola,
particularly in the construction industry. Among the construction techniques, adobe is one of the most used
in the province of Huambo, especially by low-income families, which constitute the majority. This
technique was established as an intangible heritage in the culture of that population. Huambo province is
located in the central region of Angola (Central Plateau). Adobe blocks are building elements with
potential degradation by the action of water. Due to the subtropical climate, hot and humid, and
geomorphology of the province, located at about 1000–2000 m of altitude and with an extensive river
system, these buildings can be vulnerable and may present premature degradation, exacerbated by the lack
of knowledge concerning the properties of the geomaterials used and techniques/solutions that allow their
stabilization and conservation. This paper aims to present the main results of the study to investigate the
influence on adobe performance in regard to the mineralogy and geochemistry of soils used in the
production of adobes used in the construction of dwellings. The knowledge gained with this research can
support the development of solutions for the common anomalies and problems in this construction, as well
as to improve the strength and durability of the adobe units. For this purpose, soil samples were collected
and mineralogical, geochemical, and physical tests were performed. Durability and erodibility tests were
also performed on selected adobes, following the Geelong method. The results obtained with this research
may contribute to the development of the knowledge concerning this sustainable building solution, which
has a strong presence in the province of Huambo and neighbouring regions.|
