ABSTRACT

The durability of building materials is a fundamental issue addressed by many researchers who seek to improve working life by obtaining durable and more sustainable materials. In the Canary Islands, there are traditional buildings with carpentry elements that remain unchanged, without any apparent degradation. Specifically, the wood used in Canarian heritage comes from the resinous heartwood of Pinus canariensis. Most of these buildings were built between the sixteenth and nineteenth centuries, and their architectural relevance has been decisive in declaring the city of La Laguna a World Heritage Site by UNESCO. The objective of this research is to identify the carpentry elements made with the heartwood of Pinus canariensis within the Canarian architectural heritage and to evaluate its durability. The results show that the loss of mass for the heartwood of Pinus canariensis after the incubation of the fungus was less than 1% in all cases. However, other conifers show a considerable loss of mass, between 25% and 38%.

摘要

建筑材料的耐用性是许多研究人员解决的一个基本问题，他们寻求通过获得耐用和更可持续的材料来改善工作寿命。在加那利群岛，有木工元素的传统建筑保持不变，没有任何明显的退化。具体来说，加那利群岛遗产中使用的木材来自松树的树脂心材。这些建筑大部分建于 16 世纪和 19 世纪之间，它们的建筑相关性在联合国教科文组织宣布拉古纳市为世界遗产方面具有决定性意义。本研究的目的是确定用金丝雀心材制成的木工元素在加那利建筑遗产中并评估其耐用性。结果表明，在所有情况下，真菌培养后金丝雀的心材质量损失均小于 1%。然而，其他针叶树表现出相当大的质量损失，在 25% 到 38% 之间。
