“…6. The CT Meter enables the experimental determination of the thermal conductivity and volumetric heat capacity in accordance with NF EN 993-15 of 2005, [27], [28], [29]. Thermal conductivity and bulk density (equation ( 1)) were determined for the reference sample and for samples with different percentages of iron powder waste.…”

The use of iron waste in concrete is now of considerable importance, mainly because of the benefits for the environment and for improving the strength of concrete. The increased and unused of this industrial byproducts represents a challenge for the environment and human health. This article experimentally explores the influence of utilizing iron powder waste and iron fibers in concrete in order to enhance the thermophysical properties of concrete and reduce the environmental impact resulting from iron waste. The aim of this work is to study the thermophysical properties (thermal conductivity, volumetric heat capacity, thermal diffusivity and thermal effusivity) of concrete with waste iron powder and iron fibers for application in building construction. The iron powder waste was added to the concrete with different percentages of 0%, 5%, 15%, 20% and 25% respectively as a partial replacement of sand. The iron fibers were added with mix proportions including 1.0%, 1.5%, 2.0% and 2.5% by volume of concrete, and in two different arrangements, uniform and random. The thermal conductivity and the volumetric heat capacity of these samples were measured experimentally in the dry state at ambient temperature (20 °C), and at 28 days of age. The effect of the integration of iron powder and fiber on thermal properties was analysed.

The aim of this study is, on the one hand learn about this type of wood, and on the other hand, is to study the processes the thermophysical characterization of araucaria wood from the city of el Jadida, Morocco, and on the other hand, will study the processes related to evaporation. Wood is defined industrially as an anisotropic and heterogeneous material formed over many years of a tree's life. The anatomical study of wood generally involves the examination of three directions of reference, the axial, radial and tangential directions. And a study of the constituent elements of wood being oriented in several directions, it follows from experience that its thermal properties differ in the longitudinal, radial or tangential direction, where thermophysical tests are carried out at wood moisture contents between 10 and 11%. Concerning the thermal properties, study highlighted, the determination of thermal conductivity, specific heat, thermal diffusivity and then the thermal effusivity of araucaria wood at different temperatures: 25°C, 35°C, 50°C and 60°C. The results are obtained experimentally by a device called ''CT-Metre''. He illustrated that this kind of wood is more conductive of heat in the longitudinal direction than the radial and tangential directions. Also, have determined the evaporation rate under well determined conditions, chose an enclosure to keep the set temperature, and then add NaCl to keep humidity at 75%, which also gives important results.
