Dataset on the hygrothermal performance of a date palm concrete wall.

The present data article is concerned with the hygrothermal performance at the wall scale of a new bio-based building material including date palm fibres. A specific test setup allowed to measure temperature and relative humidity (RH) profiles at three different depths of the bio-based wall subjected to outdoor boundary conditions. Besides, a partial differential equations resolution software was then used to solve two mathematical models (, Kunzel and Mendes models) describing heat and moisture transfer in porous building materials.

Controlled Emissivity Coatings to Delay Ignition of Polyethylene.

Semi-opaque to opaque films containing small amounts of various aluminium particles to decrease emissivity were easily prepared and coated onto low-density polyethylene (LDPE) sheets. The thermal-radiative properties (reflectivity, transmissivity and absorptivity) of the films were measured and related to the aluminum particles' content, size and nature. Time-to-ignition of samples was assessed using a cone calorimeter at different heat flux values (35, 50 and 75 kW/m²).
