Abstract
En el trabajo de investigación titulado Uso de ovoalbúmina como ligante de mortero cálcico aéreo en restauración de pintura mural colonial: Estudio de caso se planteó como objetivo evaluar la formulación de morteros de cal aérea con ovoalbúmina como aditivo orgánico para su utilización en la restauración de pintura mural colonial en las que se ha empleado, y cuyo análisis de laboratorio permite identificarlo. La investigación se desarrolló con un enfoque mixto y diseño secuencial (CUAN-CUAL), siendo de nivel descriptivo y tipos aplicado. Se formularon seis morteros (M1, …M6) para los que se manipularon las proporciones de los ingredientes con la finalidad de reconocer y medir sus propiedades físicas (contracción volumétrica, pérdida ponderal durante el secado, absorción de humedad, resistencia al arranque, textura y dureza final) se elaboraron cuatro probetas por mortero para los análisis respectivos, haciendo un total de 24. Se concluyó que el mortero M2 presentaba las mejores características para su utilización en la restauración del revoco superficial de la pintura mural del templo Patrón Salvador del Mundo, del distrito de San Salvador localizado de la provincia de Calca, Cusco (Perú). Para la selección se recurrió al juicio heurístico. Además, se describen las características de la pintura mural, en cuyo revoco o enlucido (intonaco) original se identificó el uso colonial de la ovoalbúmina, la iconografía, el estado de conservación y la secuencia de procedimientos llevados a cabo, como estudio de caso muestral.
In the research work entitled Uso de ovoalbúmina como ligante de mortero cálcico aéreo en restauración de pintura mural colonial: Estudio de caso aimed to evaluate the formulation of aerial lime mortars with ovalbumin as an organic additive for use in paint restoration colonial mural in which it has been used, and whose laboratory analysis has allowed to identify it. The research was developed with a mixed approach and sequential design, descriptive and applied type. Six mortars (M1, ... M6) were formulated for which the proportions of the ingredients were manipulated to recognize and measure their physical properties (volumetric shrinkage, weight loss during drying, moisture absorption, tear resistance, texture, and final hardness) in four probes per mortar, making a total of 24. It was concluded that the mortar M2, presented the best characteristics for its use in the restoration of the surface plaster of the mural painting of the Patron Savior of the World temple, in the district of San Salvador located in the province of Calca, Cusco (Peru). Heuristic judgment was used for the selection. Also, the characteristics of the mural painting are described, in whose original plaster or plaster (intonaco) the colonial use of ovalbumin was identified, the iconography, the state of conservation and the sequence of procedures carried out, as a sample case study.
