Concrete Mix Design (Design Criteria (Strength, Durability, Workability,…

- - - - Mass concrete/pavements/topping: 40 - 80 mm slump
      - Structural concrete/sidewalks/driveways/slabs: 80-100mm
      - Basic superplasticized concrete: 110-170 mm
      - Self compacting concrete (Slump Flow): 600 - 700mm
  - - - Vertical wall elements dry out quickly
      - Horizontal elements become nearly saturated
    - - Max. aggregate size affects amount of paste required; paste needs to be protected with a certain volume of air bubbles
    - - Silica fume
