Estudo do comportamento de argamassas estabilizadas no estado endurecido

Abstract

The mortar is a material widely used in civil construction, one of the uses being as mortar coat on walls. The use of stabilized mortar for wall coating has been growing in the country, however, there is still a lack of technical specifications related to its use. This research carried out tests in hardened condition in stabilized mortars with stabilization times of 24 hours, 36 hours and 48 hours in order to fulfill its objective, which was to analyze the behavior of stabilized mortars used for external and internal mortar coating. To perform the research, only the percentage of the additives was changed in order to verify their influence in the mortars. The tests were: capillary absorption, flexural strenght and compressive strenght. It was verified that the capillary coeficiente and mechanical strenght are inversely proportional and the higher is the additive, the higher is the capillary coeficiente and the lower is the mechanical strenght. It was verified that the mortar with stabilization time of 24 hours was considered adequate for the use.
