Earth and Stone, Santiago's Arquitectural Raw Materials
(Univ Diego Portales, 2016)
The first Santiago of Chile's architecture was built with foreign forms of Spanish origin, but using existing local materials that were then available in Chile's central valley. Thus, earth and stone were the walls' raw ...
Infrared Thermography technique (IRT) for the evaluation of the hydric behavior of building stones
(IMEKO-ACTA, 2018-10)
The water distribution into stone specimens in laboratory conditions is evaluated through the infrared thermography method (IRT). Porous building stones samples (calcarenite and sandstone) are examined under stable laboratory ...
Influence of dimension stones on the increase of radon gas levels indoors
(2015-01-01)
The present work features results on the possible increase of radioactive 222Rn gas in environments of human habitation, caused by the use of dimension stones inside constructions with poor air circulation. For the study, ...
Gypsum crust as a source of calcium for the consolidation of carbonate stones using a calcium phosphate-based consolidant
(Elsevier, 2017)
The high levels of atmospheric pollution in cities today are causing the decay of natural building stone,especially due to the formation of gypsum crusts on carbonate stones. For this reason we have assessedthe efficacy ...
