CO2Buster​.
Less CO2, More strength

CO2Buster™ is a graphene infused blend of sand for concrete batch applications. Formulated to reduce CO2 emissions by removing at least 10% of cement content from batch design without losing concrete strength.

  • Higher Carbon Footprint: By not choosing CO2Buster™ you’re missing out on a chance to reduce your CO2 emissions, potentially damaging yours and your customers environmental credibility.
  • Missed Differentiation in the Market: Without the unique selling point of sustainable construction, you could struggle to stand out in a competitive market, potentially losing business to more forward-thinking competitors.
  • Don’t Change Your Batching Plant: Simply replace cement volume with a much lower CO2 emission alternative, CO2Buster™.

The unique properties of graphene enable concrete strength to increase even with a reduction of cement. We achieve this with our unique blend of graphene and dry graded sand as a replacement for the cement. The result is strong concrete with reduced CO2 emission impacts.  Strength benefits are gained immediately, workability is unaffected, and CO2 is reduced.

CO2Buster™ uses graphene that is specifically designed for inclusion in cementitious composites to deliver performance enhancements. This is ideal for concrete, mortar and pumping applications. Graphene powder used is 50μm with tightly controlled geometries.
