Experimental and theoretical analysis of a cement mortar containing microencapsulated PCM

• Cement mortar incorporating a phase change material.
• Experimental and theoretical analysis.
• Correct transient simulations of the sample's behavior.
• Emphasis and discussion of the error committed with a pure substance model.

This article deals with the study of a mixture of a cement mortar with a phase change material. We performed together an experimental analysis and a theoretical modeling of the sample associated with transient simulation of its behavior when a heating or a cooling is imposed to this later one. A non pure enthalpy profile is supposed, which permits to better describe the measurements. Furthermore, the drawbacks no to use such a method in order to prefer a more classical one are pointed out.
