- - - - Characterise what changed to facilitate improvement
        
        Water absorption
        
        Heat of hydration
        
        Slump
      - Mineralisation
        
        Hypothesis: improves strength and sequesters
        
        Conditions: T and P
        
        90'C
        
        200'C
      - SCM blending
      - Grinding aids
    - - Mineralisation needn't benefit strength,
        but can improve C sequestration
    - - Mineralisation will need to have
        a big impact on strength
    - - Multiple ways of improving strength
        likely required
  - - - 50 um
      - 20 um
      - 100 um
      - 200 um
      - Strength improves
        
        Incorporate into methodology
        going forward
      - Strength worsens
        
        Consider using kimberlite as
        aggregate/sand replacement instead
        
        Try mineralisation on 10 um
