Title: Complete Recycling and Utilization of Waste Concrete to Produce New Structural Concrete

 

Invention: The invention is a novel process for recycling waste concrete to create a geopolymer concrete. This method provides complete recycling and utilization of waste concrete, both aggregates and fines, to produce a new structural concrete. It does so without the use of conventional energy intensive processes and the large carbon footprint produced by Portland cement.

 

Background: Portland cement is commonly used as a binder in the production of concrete. Unfortunately, this Portland cement releases greenhouse gases and is can have a large carbon footprint. Because current methods produce inferior strength and durability, there is a need to recycle waste concrete and simultaneously reduce environmental impact.

 

Applications:

  • Construction
  • Recycling
  • Waste management

 

Advantages:

  • Reduced carbon footprint
  • Reduced energy requirements
  • Meets unconfined compressive strength values
  • Reduced quarrying operation costs
