Abstract

Ceramic brick as a building material is used in many civilizations worldwide. In the case of the Historic Center of Cuenca (Ecuador), it dates back to colonial times and remains as a determining factor in local identity. However, beyond the productive tradition, its technical conditions of knowledge, use, and conservation are limited. In this context, the present research resorts to analytical techniques to characterize the raw material and solid brick from historical production and historical supply sites. It is determined that there are significant variations in composition, physical and mechanical behavior and durability. Thus, the low compressive strength (x̄ = 5,87 MPa) and low bending strength (x̄ = 0,13 MPa), high open porosity (36–37 %) and water absorption (17–20 %), open an important discussion on the conservation conditions of the numerous heritage buildings built in brick, as well as on the implications for the artisanal production process.
昆卡(厄瓜多尔)的手工砖:遗产框架内的初步特征
陶瓷砖作为一种建筑材料,在世界上许多文明中都有使用。就昆卡(厄瓜多尔)历史中心而言,它可以追溯到殖民时代,并且仍然是当地身份的决定性因素。然而,在生产传统之外,它的知识、使用和保存的技术条件是有限的。在这种情况下,目前的研究采用分析技术来表征历史生产和历史供应地点的原材料和实心砖。确定在成分,物理和机械行为以及耐久性方面存在显着变化。因此,低抗压强度(x ' = 5.87 MPa)和低抗弯强度(x ' = 0.13 MPa),高孔隙率(36 - 37%)和吸水率(17 - 20%),开启了对众多砖砌遗产建筑保护条件的重要讨论,以及对手工生产过程的影响。

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.
