About CarbiCrete

CarbiCrete is a Montréal-based clean-technology company developing cement-free concrete products using steel slag and CO₂ curing. The company conducts applied research, materials testing, quality control, process development, and pilot-scale validation of low-carbon concrete technologies.

CarbiCrete is seeking a Materials Testing Technologist – Concrete R&D; to support specialized testing, characterization, process development, and quality-control activities involving concrete, aggregates, steel slag, industrial mineral by-products, and carbon-cured construction materials.

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, such as:

- Materials Engineering or Materials Science;
- Civil Engineering or Civil Engineering Technology;
- Chemical Engineering;
- Mining, Metallurgical, or Mineral Processing Engineering; or
- another closely related engineering or technical discipline involving construction or mineral materials.

A university engineering degree is considered an asset where it includes substantial laboratory or construction-materials experience.

Professional Experience

A minimum of 2 years of directly
