Determinación de las propiedades térmicas de un mortero modificado con sargazo como material alternativo en construcción

Abstract

In the present work we analyze the properties of a mortar with the addition of treated sargassum algae, replacing the stone aggregate in percentages of 5%, 10%, 15% and 20% in order to reduce the thermal conductivity of the coating and the thermal load of the interior of the buildings, thus reducing energy consumption and implementing sustainable materials to the construction industry. For the purposes of this investigation, a characterization of the components of the mortar was carried out, the stone aggregate and the sargassum treated for its use as an aggregate. Samples were prepared for each percentage and compression resistance tests were performed at 3, 7, 14 and 28 days to analyze the behavior of the mortar during the hardening process. Adhesion tests were performed to determine if the mixtures are efficient for use as a coating. Subsequently, the thermal transfer was evaluated by conduction and convection. The material showed hydrophilic characteristics, therefore, the analysis of the mechanical properties showed as bigger substitution of sargassum, low is the resistance, limiting the efficient percentages to 5 and 10% for its use.
