07 Assessment

Advantages

  • At least 60% CO2 reduction vs OPC (reported for Zeobond E-Crete)
  • Compressive strength classes 20-65 MPa (Uniquecem LCC)
  • Fire rating >4 hours reported for 150 mm slab (E-Crete)
  • Uses fly ash/slag-based binders
  • Lower-carbon alternative to OPC concrete

Constraints

  • Limited Australian manufacturers (QLD, VIC)
  • Requires Performance Solution for NCC compliance
  • Higher initial cost than conventional concrete
  • Alkali handling safety requirements
  • Variable performance with precursor sources
  • Limited industry familiarity and design guides
  • Custom formulation often required
  • Heat curing may be needed for optimal properties
