Materials Testing Technologist – Concrete R&D Main Responsibilities Construction Materials Testing and Quality Control Conduct and document laboratory testing of concrete, masonry materials, aggregates, steel slag, and other industrial mineral materials. Perform physical and mechanical testing including compressive strength, density, moisture, absorption, particle-size distribution, and other applicable durability or performance tests. Inspect and evaluate raw materials and finished concrete products against internal specifications, test methods, and applicable CSA or ASTM requirements. Identify material or process deviations and assist with technical investigations and corrective actions. Concrete Mix and Materials Development Prepare, batch, and evaluate experimental concrete formulations incorporating steel slag, aggregates, mineral by-products, and alternative binder systems. Support the development and adjustment of mix designs based on material properties, workability, compaction behaviour, curing conditions, strength development, and product performance. Support laboratory-to-pilot-scale validation of new formulations and production procedures. Troubleshoot laboratory curing equipment, environmental sensors, gas-delivery systems, and associated data-acquisition equipment. Materials Characterization Support characterization of steel slag, aggregates, alternative binders, and reacted materials using laboratory and analytical techniques. Interpret material-characterization results obtained from techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), and thermogravimetric analysis (TGA) in support of concrete formulation and quality-control investigations. Correlate mineralogical, chemical, and physical material properties with concrete processing behaviour and product performance. Evaluate material variability between industrial raw-material sources and identify its potential effect on concrete production and curing. Experimental Data Analysis and Technical Documentation Design and execute structured laboratory trials and experimental test matrices. Collect, validate, organize, and analyze experimental and quality-control data. Prepare graphs, technical summaries, test reports, laboratory records, SOPs, and experimental documentation. Compare experimental results across different raw materials, mix designs, curing conditions, and production trials. Maintain accurate traceability of samples, materials, test conditions, and laboratory results. R&D Support Support pilot-scale concrete production and process-validation activities. Assist engineers and researchers with equipment setup, testing programs, technical investigations, and process-development projects. Coordinate laboratory testing with external laboratories, equipment suppliers, or technical service providers when required. Assist with calibration, maintenance, and verification of laboratory and pilot-scale testing equipment. Required Qualifications Education A post-secondary qualification in a field directly related to construction materials or materials testing is required. Professional Experience A minimum of 2 years of directly relevant hands-on laboratory or industrial experience involving construction materials, concrete, aggregates, mineral materials, or closely related materials-testing activities is required. Technical Requirements The candidate must demonstrate: Hands-on ability to operate, calibrate, and troubleshoot construction-material testing equipment. Experience following standardized laboratory procedures and maintaining accurate experimental records. Ability to interpret numerical test results and identify relationships between raw-material characteristics, process conditions, and product performance. Experience preparing professional technical reports, laboratory documentation, graphs, and test summaries. Ability to work safely with industrial mineral materials, laboratory equipment, pressurized gases, and controlled environmental eq…
