Researchers have found that concrete can be made 30% stronger by replacing a percentage of sand with spent coffee grounds, an organic waste product produced in huge amounts that usually ends up in ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

While compressive strength is key to overall product viability, the reduction of CO 2 emissions achieved by using PyroGenesis’ plasma technology, a low carbon emitting process, has the potential to ...
