  1. Risk Reduction IntroducingSynthetic Pozzolan

  2. Global Cement Forecast Image reprinted with permission from the Portland Cement Association Titel

  3. What are SCM? Supplementary Cementitious Materials Image reprinted with permission from the Portland Cement Association Titel Substitution of clinker in cement by another material which has Cementitious properties

  4. SCMs Categories • Hydraulic • Pozzolonic Classifications • Natural • Synthetic • Waste Material Benefits • Environmentally friendly sustainable products • Lower Fuel Consumption • Lower Operating Costs • Lower Capital Costs

  5. Typically Used SCM Fly Ash Silica Fume Slag

  6. Clays Based SCMs Q (t, T) Q (t, T) Titel Crystalline Clay • Organized Structure • Stable / Non-reactive Amorphous Material • Disordered • Highly Pozzolonic Collapsed Clay • Partially Crystalline • Stable / Non-reactive

  7. Calcination / Activation Titel

  8. Clay Based SCMs Titel

  9. Clay Based SCMs Titel Final strength Low early strength Color Water demand Emissions (Process)

  10. Laboratory Study Titel Synthetic Pozzolan With the objective of identifying potential to produce a synthetic pozzolan from a given clay: • Sample Preparation • Chemical and mineralogical characterization • Physical testing • Activation utilizing calciner process • Color control of product • Grinding and physical testing of synthetic pozzolan • Compressive strength testing at three substitution rates (20, 30 and 40%)

  11. Direct Substitution Titel

  12. Blend Optimization Titel Clinker is engineered for Ordinary Portland Cement Blended Cement can mimic Ordinary Portland Cement High substitution rates require different parameters Optimization of physical and chemical properties required Blended Cements ~ Ordinary Portland Cement

  13. Market Acceptance Titel • Mobile Plant • Pilot scale Pozzolan Calciner System • 5 MTPD capacity • Fully integrated / Self-sustainable (Plug-and-Play concept) • Simple set-up & operation • Advantage • Hands-on experience • Product produced with available raw materials • Capacity to achieve consumers acceptance • Investment • <1% of Industrial Installation

  14. The Mobile Plant Titel

  15. Thank You Titel
