Evaluación resistográfica en elementos de maderas desfibradas de la torre de lixiviación de la oficina salitrera Santa Laura en Chile. Patrimonio de la Humanidad

The leaching tower is located in the Santa Laura saltpeter works office in Chile. In recent years studies have been carried out, using Non Destructive Techniques (TND), which have determined that the tower is in good condition. However, there are doubts regarding the actual dimensions of the construction elements affected by the desfibration. The present study had the objective of evaluate defibred wood elements, from the leaching tower of the Santa Laura saltpeter works office, using the resistography technique. Additional studies of ultrasound and xylohigrometry were also developed. The obtained results establish that the reduction of the dimensions of the evaluated elements does not present significant difference and that there are no deep damages in the woods. The study confirms that the building is not at risk.
