Single layer mortars with microencapsulated PCM: Study of physical and thermal properties, and fire behaviour

Abstract

Phase change materials are a promising strategy to reduce energy consumption in a wide range of applications including the building sector. Many studies have been done to evaluate the impact of PCM on thermal properties of building materials, however there exists little information on the influence of PCM on other properties of the support materials. This knowledge is necessary to determine the feasibility to apply and use building materials containing PCM. In this paper, the effect of the addition of different percentages of microencapsulated phase change material on the properties of two commercial single layer mortars has been studied. Physical and thermal properties as well as fire reaction have been evaluated.
