Description du poste

QUI EST HOLCIM ?

QUI SONT LES GENS DE HOLCIM

THE OPPORTUNITY - CONTEXT OF THE MISSIONS

The Holcim Innovation Center focuses on enhancing the performance, cost-efficiency, and sustainability of our cement production processes globally. The strategic adoption of advanced process additives is crucial for accelerating our low‑carbon transition. This mission is vital to reinforce our in‑house expertise, allowing us to accurately tailor and develop optimized additive blends for our global operations.

The intern will be a key contributor, bridging advanced chemical analysis and cement performance testing:

• Advanced Chemical Characterization: Lead a project focused on the in‑depth chemical characterization of complex, multi‑component process additives currently used in the cement industry.
• Formulation Development and Optimization: Utilizing the data generated from the chemical analysis, the intern will be responsible for developing and optimizing alternative formulations and blends from readily available industrial raw materials.
• Strategic Performance Testing: Conduct a rigorous performance evaluation of these developed formulations on Next Generation Cements. This includes testing efficiency under process conditions (e.g., in grinding) and assessing effects on cement properties (flowability, strength).
• Process Standardization: Document the validated formulations, testing methods, and critical parameters, contributing directly to the Group's internal technical guidelines for additive handling and blending.

MISSIONS

• Systematically process and interpret advanced analytical data (LC/GC/MS, FTIR, etc.) for complex organic mixtures
• Execute laboratory work to design, blend, and ensure the physicochemical stability of new liquid additive formulations
• Perform performance tests (e.g., grinding efficiency, flowability, strength) on various cement types
• Synthesize findings into actionable technical recommendations for business units

DESIRED PROFILE

DESIRED SKILLS

Technical skills / Knowledge:

• Background in Organic Analytical Chemistry (ability to interpret complex spectra/chromatograms is required)
• Proficiency in Formulation and liquid stability/blending protocols
• Scientific rigor
• Autonomy
• Strong analytical capacity

EDUCATIONAL LEVEL: TRAINING

• Master's degree or final year of Chemical Engineering School: Chemistry, Materials Science, Chemical Engineering, or Physico‑Chemistry
• Spoken languages: Fluent in French and in English

FURTHER INFORMATION

Duration: 6 months.

Start date: February / March 2026.

Holcim site (Holcim Innovation Center): Saint‑Quentin‑Fallavier, approximately 30 km east of Lyon (accessible by public transport).
