Analizar el revoque de tierra, resistente a la disgregación de sus partículas finas

Abstract

In vernacular architecture, the final earthen layer is used to protect and finish surfaces. This practice has been common in the Sierra region of Ecuador since ancient times, as well as in other parts of the world. The purpose of this analysis is to examine methods for optimizing the characteristics of the mixtures used in surface renders, to significantly improve resistance to external stresses. To this end, conventional techniques are considered, along with the materials and methods available in the province of Cañar, Ecuador. The measurement of compressive strength is essential to assess the quality of the different mixtures tested, as it determines whether these mixtures are suitable for use in the final coating layer. The results show that the inclusion of natural additives influences the disintegration of fine particles in earthen plaster mixtures. The differences in compressive strength among the various types of mixtures and the original mixture demonstrate this and make it possible to define the optimal composition.
