Impact of phase change materials on lightened earth hygroscopic, thermal and mechanical properties

Climate change is leading construction engineers and building stakeholders to improve materials thermal insulation heat storage capacity. The development of energy efficient with a low environmental impact real challenge. In this sense, earth-based are known worldwide have been used since thousands years. These present many advantages but their deployment on large scale, while respecting the operative standards, still limited. Considering lightened earth, work aims properties by using phase (PCM). incorporation PCM in has aroused great interest due capacity store energy. study, mechanical, hygrometric experimental studies were carried out soil-fiber-PCM mixtures. showed an interesting improvement earth deterioration keeping mechanical relatively unchanged.
