Abstract

The objective of the present work is to analyze the influence of the lightweight concrete block support on the physical and mechanical characteristics of the applied mortar. This work aims to understand how the physical and mechanical properties of the mortar are modified by the support. The methodology used consisted of conducting laboratory experimental tests to compare the behavior of mortar molded in standard moulds with the behavior of mortar applied to lightweight concrete block supports. Open porosity, bulk density, capillary water absorption, water vapor permeability and compressive strength were studied. These results have shown how the support influences the characteristics of the mortar, improving the understanding of the performance of the applied mortar. This study provides a global approach to the assessment of mortar characteristics, considering the analysis and comparison of mortar applied to the support and molded in the laboratory, according to current standards. Such understanding may contribute to the reassessment of the way mortars are produced, seeking to optimize their characteristics and compatibility with the support.
