Additional related data not included in this dataset: N/A – not applicable METHODOLOGICAL INFORMATION ----------------------- 1. Description of the methods used to collect and generate the data: The data were collected using various standardized laboratory techniques to assess the properties of slate waste (SW) and its application in cement mortars. The methods used include: X-ray Diffraction (XRD) to identify mineral phases, performed with a Bruker D2 PHASER 2nd Generation device using Cu Kα radiation (5–60° angle 2θ, step size 0.04, count time 3 s). X-ray Fluorescence (XRF) for determining the chemical composition, carried out with PANalytical Epsilon3X equipment. Loss on Ignition (LOI), calculated per EN 196-2 by heating 5 g of material to 1050°C and measuring mass loss. Fourier Transform Infrared Spectroscopy (FTIR) for analyzing mineralogical and pozzolanic properties of slate using a VERTEX-70V from Bruker in diffuse reflection mode. Mechanical testing (compressive strength) following EN 196-1, comparing mortars with and without 20% cement replacement with calcined slate waste. Pozzolanic activity tests (Frattini and Saturated Lime tests), which assess ion concentrations in the samples with results plotted for [OH⁻] and [Ca²⁺]. The experimental design and protocols followed international standards (ISO 14040, ISO 14044+A1) for environmental impact assessments and cement composition evaluation. 2. Data processing methods: The raw data from the tests were processed to derive key metrics for cement performance and environmental impact. For the XRD and FTIR data, mineral phases were identified by analyzing peak positions and intensities. The XRF results were converted to oxide composition. LOI was calculated using mass changes before and after ignition. The mechanical strength tests generated compressive strength values from which the Strength Activity Index (SAI) was calculated. Data from pozzolanic activity tests were plotted on concentration graphs to evaluate the reactivity of calcined slate at different temperatures. For the life cycle assessment, the CML 2001 method was applied to assess environmental impacts based on inputs and outputs for 1 tonne of cement production. 3. Software or instruments needed to interpret the data: XRD and FTIR results were interpreted by Originlab 9 software. XRF results was interpreted by PANalytical Epsilon3X software. Compressive strength testing, Strength Activity Index, Frattini and lime saturation tests were performed and interpreted Microsoft Excel. LCA was performed and interpreted using Microsoft Excel. 4. Information about instruments, calibration and standards: All instruments were calibrated according to manufacturers’ guidelines and relevant standards. The equipment used to perform XRD ( Bruker D2 PHASER) was calibrated using a silicon standard, ensuring accurate diffraction angles. The machine used to perform XRF (PANalytical Epsilon3X) was calibrated against certified reference materials for oxide quantification. The equipment used to perform FTIR (VERTEX-70V from Bruker) was verified with a polystyrene film to verify wavelength accuracy. In addition, the compressive strength equipment (EMIC DL 20000) was calibrated with load cells certified by the Brazilian calibration system (INMETRO). 5. Environmental or experimental conditions: The tests were conducted in controlled laboratory conditions with stable temperature (22 ± 2°C) and humidity (45–55%) to ensure consistent results. During the Frattini and saturated lime tests, samples were stored at 40°C to promote pozzolanic reactions. Atmospheric conditions were monitored to avoid external factors influencing the experiments, especially during XRD and FTIR analyses. 6. Quality-assurance procedures performed on the data: - Duplicate samples were tested for each measurement to ensure reproducibility. - Cross-checking of results with different testing methods (e.g., comparing pozzolanic activity results from Frattini and FTIR tests). - All data were validated by comparing experimental values to literature references and standards. The life cycle assessment followed ISO standards to guarantee reliable environmental impact analysis. FILE OVERVIEW ---------------------- 1.
