In the last years, the sensitivity towards environmental impacts of industrial activities is of growing interest. Construction sector, with particular reference to cement-based materials, possesses a high environmental footprint due to raw resources’ consumption and waste, energy use, greenhouse gasses emissions produced during the preparation of the construction materials and the building and service life of structures. A possible solution to decrease the impact of cementitious building materials is to develop novel multifunctional eco-friendlier binders for enhancing the thermal properties and sustainability of the material. The composite investigated in this paper is an earth cement composite doped with carbon microfibers, named “smart-earth concrete”. The material’s binder is composed by both cement and clay, in the proportion of 2/7 in volume. The carbon micro-fillers are added in order to enhance the sensitivity of the composite and provide multifunctional properties, such as sensitivity to mechanical strain and changes in physical conditions. The thermal and sensing capabilities of the smart-earth concrete are investigated through dynamic environmental tests and electrical acquisitions carried out on samples in thermal chamber under controlled changes in temperature and humidity. The innovative earth-cement composite demonstrated good thermal energy storage potential. Moreover, the electrical monitoring of the smart material allowed to properly identify temperature and humidity environmental fluctuations. The proposed composite appears promising for application in real-scale constructions, enhancing the energy efficiency of the structures and providing sensing capability for their monitoring during their service life.
