Symposium Topics

High temperature processing and engineering of residues

  • Physical properties: viscosity, diffusivity, density, surface and interfacial tension, thermo-conductivity, electric-conductivity, thermal expansion coefficient, optical properties of slags
  • Thermodynamic properties: activity for slag systems, slag capacities (sulphide capacities, phosphate and phosphide capacities, etc. Solubility of solid compounds in liquid slag)
  • Hot stage slag engineering
  • Slag composition modification for added value application
  • Hot stage slag carbonation
  • Heavy metal immobilisation
  • Volume stability
  • Internal slag recycling and other solid wastes utilisation in metallurgical process
  • Slag engineering to optimise metallurgical process (e.g. protect lining brick from degradation,…)
  • Slag formation, slag foaming, slag minimisation in the process
  • Controlled slag cooling and microstructure
  • Freeze lining
  • CCT and TTT curves of slag, crystal precipitation and growth kinetics
  • Mold slag solidification during continuous casting
  • Dry quenching to recover heat from high temperature slag
  • Harvesting enthalpy in slag
  • Recovery of base metals, recovery of rare earth and precious metals
  • High temperature processes
  • Mineral processing: magnetic separation, gravity separation, flotation separation, etc.
  • Clean slag production: slag design for zero waste metallurgy, deep reduction, plasma fuming, leaching, removal of harmful component from slag, etc.

Valorisation of slags and residues in construction materials and novel applications

  • Slag engineering for new binders
  • Slag comminution
  • Cements incorporating residues
  • New clinkers (belite, sulfo-aluminate, sulfo-ferrite, etc.)
  • High temperature residues as supplementary cementitious materials
  • Alkali-activated materials, inorganic polymers, geopolymers
    • Synthesis
    • Alternative activators
  • Carbonation processing
  • Hybrid cements
    • Characterisation
    • Alternative activators
  • Ceramics from high-temperature residues
  • Admixtures for cementitious materials
  • Modelling (thermodynamic, statistical, computational)
  • Advanced characterisation techniques and tools
  • Novel processing routes (e.g. additive manufacturing, microwaving, coatings, pigments, etc.)
  • Novel applications of cementitious materials (e.g. catalysis, etc.)
  • Porous materials for sound and heat insulation
  • Durability aspects of new binders
  • Leaching aspects of residues and binders
  • Real-life validation of new binder systems

Legal and environmental bottlenecks and opportunities for slag-based products valorisation

  • Standardisation of slag-based products: Need for internationally accepted standards for slag-based construction materials.
  • Recyclability of slag-based construction materials: Need to understand the long-term behaviour of slag-based materials (recyclability second life cycle, possible re-mobilisation of heavy metals)
  • Carbon footprint of slag-based products, potential as carbon sinks: Understand the environmental balance or carbon footprint (LCA or else) of slag-based material compared to traditional construction materials. Understand their capacity to act as carbon sink (e.g. carbonation)
  • By-product or waste? Need to define the legal status of industrial slag, to strengthen their position and their value in the market.

Innovation and entrepreneurship in the raw materials sector

  • Start-up and innovative ideas
  • New business model
  • Market trends, analyses and forecasts
  • Case studies of products in the market

Workshops

The day before the start of the 6th International Slag Valorisation Symposium, two half-day workshops dedicated to the use of a particular techniques to valorise industrial by-products and residues are organised. We invite both the Symposium participants and other interested persons to register for these workshops on the April 1, 2019 through the online registration tool. To ensure the possibility of the participants to interact with the lecturers, the number of participants to each workshop is limited to 25.

Plant visit

On Friday 5 April, you have the option to go along on post-conference tour to either Orbix or Metallo.

Orbix develops and sells sustainable materials and technologies for the construction and steelmaking sector. The company has the single ambition to be a zero waste company, thereby striving for an optimal (re-)use of materials. The participants of this plant visit will have the chance to visit the facility in Farciennes, where they will see the carbonation technology applied to steel slags.

Metallo is a recycling and refining company, which valorises complex non-ferrous materials by returning metals back into the value chain. Participants to this plant visit will have the opportunity to visit Metallo’s production facilities in Beerse.

The number of participants for each plant visit is limited to 50. You can register for this event using the registration form.

Social Events

Symposium dinner

The symposium dinner will take place on Wednesday April 3, 2019 at Salons Van Dijck, in the historical city centre of Mechelen.

Museum visit & lunch

On Tuesday April 2, 2019, there’s a free excursion to the Hof van Busleyden museum, where you will be offered a lunch and a guided tour.

Workshop excursion

All workshop participants can take part in an evening visit of the famous tower of the St. Rumbold’s Cathedral with a reception on top on Monday April 1, 2019.
