(Historical and technical material research; Quito, Ecuador and London, UK; 2003)

The dramatic volcanic eruption of the Reventador in November 2002 in Ecuador, which deposited large amounts of volcanic ash on the city of Quito, was the starting point of this research project.

Extensive study on the specific chemical and physical properties of the ash lead to the conclusion that it could be stored in heaps and used as a construction material based on its cementicious properties.

This project was carried out as a research programme at the Architectural Association in London, in collaboration with the Civil Engineering department of Ove Arup, the Roman Era studies department at the British Museum, the Civil Guard of Ecuador and the National Geophysics Institute at the Polytechnic university of Quito.
