Effect of Ecological Insulating Fiber on the Thermal and Mechanical Properties of Plaster

摘要

This paper is an investigation of the thermal and mechanical properties of new insulating materials plaster-fiber alpha so as to use it in the ceiling on building construction. For this reason, many samples were produced for different percentage of fiber alpha so as to define the best percentage of fiber alpha which assures adequate thermal and mechanical properties. Also, the thermal and mechanical characterization was done using the asymmetrical hot plate, flash, and three flexure points' methods. Moreover, experimental results of thermal conductivity were confronted to different theoretical models to know the nature of fiber alpha distribution inside the matrix plaster. Furthermore, thickness of heat flow diffusion was studied so as to see the effect of the developed samples on the thermal inertia of a ceiling.
