Complementary dataset for "Integrating agro-industrial waste in clay-based porous ceramics for eco-friendly cooling applications"
Description
This dataset presents detailed experimental data on the development and characterization of ecofriendly porous ceramics made from natural clay, rice husk, and recycled ceramic waste, aimed at applications in passive and evaporative cooling systems. It includes measurements of apparent porosity (%), bulk density (g cm⁻³), linear shrinkage (%) (drying and firing), water absorption (%), thermal conductivity (W m⁻¹ K⁻¹), thermal diffusivity (mm² s⁻¹), compressive strength (MPa), and flexural strength (MPa) for seven different mixtures (M0–M6) fired at 900°C, 1000°C, and 1100°C. Additional data include the permeability coefficient and capillary absorption coefficient of fired products, as well as cooling performance metrics under varying air velocities to assess thermal-hygrometric behavior. The dataset also provides mineralogical data from X-ray diffraction (XRD) analyses and thermal properties derived from DTA/TGA of the raw materials. These data support research on sustainable construction materials and energy-efficient cooling technologies.

Steps to reproduce
The data were generated through a systematic experimental process involving the formulation, fabrication, and characterization of porous ceramic specimens made from clay, rice husk powder, and ceramic waste powder. Seven mixtures (M0–M6) with varying proportions of these raw materials were prepared, shaped into standard specimens, dried, and sintered at three different temperatures (900°C, 1000°C, and 1100°C). Standard laboratory procedures were used to evaluate physical properties such as bulk density, apparent porosity, water absorption, and linear shrinkage (drying and firing). Mechanical performance was assessed through compressive and flexural strength tests using a universal testing machine. Thermal conductivity and diffusivity were measured using a KD2 Pro thermal analyzer. Permeability and capillary absorption coefficients were determined following ASTM C577 and UNI 11060 protocols, respectively. Mineralogical composition was analyzed by X-ray diffraction (XRD), and thermal behavior of the raw materials was assessed using differential thermal analysis and thermogravimetric analysis (DTA/TGA). Data were recorded and analyzed using R software for statistical processing and plotting. The entire methodology ensures reproducibility and adherence to recognized material testing standards.
