ABSTRACT
The new millennium general tendency of energy saving and effort making for nonrenewable resources reduction in all humankind activities implies development of more efficient products and technologies, advanced solutions and permanent improvement in all directions, including the construction field. Considering its magnitude, importance and also its impact in our everyday life, civil infrastructure and its means (resources and energy consumption, materials, technologies and procedures) represent a strategic pillar in the concept of sustainability. Special attention must be given to general preservation of structural and non-structural construction elements against natural and artificial degradation, which can affect the safety and the quality of life; the better prevention the less maintenance and repair costs involved. From this perspective the buildings external coatings are essential; representing buildings outer skin, they are thermo insulation barriers and protective layers and against aggressive agents, fulfilling both decorative and protective role. As consequence, the development of external renders as coating materials and their performances evaluation represent important although indirect topics in general ecology agenda [1]. The aim of this paper is to present the second set of results of the experimental program performed upon plasters based on organic binders, regarding the hygro-thermal properties of these coating materials. The experimental procedure started in 2012 and the first results were presented in the 13th International Multidisciplinary Scientific GeoConference SGEM 2013 [2]. The present paper shows later utcomes, concerning the same type of products and the hygro-thermal characteristics (liquid water permeability), essential for moisture transfer mechanisms and determined according to the standardized method [3], as requested by recently occurred (July 2009) of the “harmonized” European standard EN 15824 [4].
