The Frontier of Reinforced Materials: Why Joining Adfil’s R&D Lab in Zele Elevates Your Materials Science Career in Belgium (2026)

The global construction sector is undergoing a massive transformation toward decarbonization, crack reduction, and extended structural lifespan. At the center of this evolution is high-performance fiber reinforcement for concrete. This Concrete Laboratory Technician role within the Research & Development (R&D) department at Adfil Construction Fibers in Zele places you right at the testing bench of modern civil engineering materials.

Adfil is an internationally recognized specialist in synthetic fiber solutions for concrete reinforcement, backed by the industrial powerhouse Saint-Gobain Group. Working within this specialized R&D environment gives technical professionals and concrete enthusiasts direct access to advanced testing apparatus, innovative polymer-matrix formulations, and global research standards.

The Saint-Gobain Advantage: Global Resources, Focused Innovation

Being part of the Saint-Gobain family means your laboratory work is supported by world-class industrial backing while retaining the agility of a focused development unit:

• Cutting-Edge Testing Environment: Access specialized lab equipment designed to evaluate fresh and hardened concrete properties, tensile strengths, and fiber dispersion.
• Meaningful Sustainable Impact: Participate in developing micro and macro fibers that directly reduce steel mesh dependency and lower the carbon footprint of structural precast and flooring.
• R&D Collaborative Culture: Work directly alongside specialized material scientists, polymer engineers, and technical sales advisors who value empirical testing and data accuracy.

Core Daily Responsibilities in the R&D Lab

• Formulating, mixing, casting, and curing concrete test specimens according to strict European (EN) and ASTM testing standards.
• Conducting standardized fresh concrete tests (slump flow, air content, density, and rheology) and hardened concrete evaluations (compressive strength, flexural toughness, and shrinkage).
• Analyzing the mechanical behavior and matrix bonding of synthetic construction fibers within various cementitious blends.
• Documenting experimental test data systematically, preparing laboratory reports, and presenting findings to the R&D engineering team.
• Calibrating laboratory testing machines and maintaining immaculate quality and safety protocols in the lab.

Ideal Candidate Profile & Work Eligibility

This opening is designed for individuals who combine practical laboratory precision with an authentic curiosity for how concrete and binder technologies perform under stress:

• A genuine passion for concrete technology, civil engineering materials, or technical laboratory testing.
• Methodical analytical thinking, high attention to test reproducibility, and clear documentation skills.
• Mandatory Requirement: Applicants must hold the legal right / valid work permit to work in Belgium.

Working in Zele (East Flanders Industrial Triangle)

Zele is strategically located in East Flanders right along the E17 corridor, making daily commutes smooth from Ghent, Sint-Niklaas, Lokeren, Dendermonde, and Aalst. Avoiding the intense central gridlocks of Brussels or Antwerp, the location offers an ideal balance of accessible living and proximity to major Flemish industrial innovation clusters.

If you are ready to apply your technical curiosity to next-generation construction materials inside an internationally recognized group, this position at Adfil is an exceptional career move.
