“Evaluación comparativa de morteros de mampostería contra morteros que contengan cenizas del volcán Sangay como material cementante suplementario”

Abstract

The objective of this research was to comparatively evaluate ordinary masonry mortars against mortars that contain ash from the Sangay volcano as a supplementary cementing material through direct investigation in national digital journals, documents posted on the web and through laboratory tests under the NTE INEN standards. 2380, ASTM C1157, NTE INEN 2518 and ASTM C270. The bibliographic analysis showsthe problem of environmental contamination existing during the cement production process, so this study seeks to implement as an alternative the use of a percentage of ash in this cementing material, consequently also the mortar, the qualitative methodology was applied and quantitative, supported by analysis of laboratory results, uncontrolled observation, inductive exploration, among other methods; as support for the development of each of the points raised for the advance on the Comparative Evaluation of masonry mortars against mortars that contain ash from the Sangay volcano as supplementary cementing material. It was possible to establish a relationship between technique and science within the treated subject and it is evidenced that ash can be used in low proportions in conjunction with cement to obtain a similar workability, comparing its results with industrialized mortars.
