Waste Concrete Recycling

Complete Recycling and Utilization of Waste Concrete to Produce New Structural Concrete Tech ID: UA17-175 Invention: This 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, Portland cement releases greenhouse gases and has 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.
