GCCRN Projects – Recycling / Recarbonation 

CO2 emission can be decreased by recycling cementitious materials or by capturing CO2 in carbonated concrete, which is also known as a natural process. 

Core and Partner Projects

Core Projects 

  1. LCCA/LCA for the comparison of different methods of recycling concrete 
  2. Production and usage of carbonated or uncarbonated RC Fines

Partner Projects 

  1. Carbonation curing of cementitious systems (C3S): New binders and concrete recycling 
  2. Enhancing the properties of fine recycled aggregate concrete (FRAC) 
  3. Mechanical properties of concrete with recycled concrete fines 
  4. Mechanism on Enhancement of Recycled Concrete Aggregates (RCA) and Recycled Aggregate Concrete (RAC) by Accelerated Carbonation 
  5. Recycling (Mixed) Concrete Streams for Optimal Reuse
