Abstract

In conservation, earth renders can be used as sacrificial coatings. However, earth presents vulnerability when in contact with water. The application of ecological surface treatments on earth renders can be of great relevance, ensuring their durability while increasing eco-efficiency and extending its range of applications. The behaviour of a ready-mixed earth render applied in situ, on adobe and concrete block masonry experimental walls exposed outdoors with protection, and under controlled laboratory conditions, on hollow bricks, was evaluated after four years. Several superficial treatments were applied on the renders: linseed oil, mucilage of aloe vera and pasta and rice cooking water. The renders were characterized by non-destructive tests. The surface treatment with linseed oil presents good results and improves the durability of the earth render, giving it adequate protection against natural degradation.
土渲染中自然老化和生态表面处理的评估
在保护中,大地渲染可以用作祭祀涂层。然而,当与水接触时,地球呈现出脆弱性。在地球渲染上应用生态表面处理可以具有很大的相关性,在确保其耐久性的同时提高生态效率并扩大其应用范围。四年后,在室外暴露的土坯和混凝土砌块实验墙上,以及在受控的实验室条件下,在空心砖上,就地应用预拌土渲染的行为进行了评估。几种表面处理应用于渲染:亚麻籽油,芦荟胶和意大利面和大米煮水。渲染的特点是进行了无损测试。亚麻籽油的表面处理效果很好,提高了土质的耐久性,使其能够充分防止自然降解。

期刊介绍: Conservar Património is a journal, published three times a year, that intends to create a space for the diffusion of conservator-restorers’ studies and activities. However, at a time when Conservation-Restoration pretends to develop further through collaboration with other areas of knowledge, such as History of Art, Archaeology, Museum Studies, Chemistry, Physics, Biology and other related disciplines from the fields of the natural and social sciences, the journal also receives contributions from any other provenance as long as directed towards the multiple dimensions of the works that integrate our Cultural Heritage. Theoretical issues on the conservation activity may also be submitted.
