K20

K20™ is designed to partially replace OPC for the highly practical application of simply ‘making’ concrete, for any purpose. The scientifically recommended application is OPC 70% : K20™ 30%. K20™ can be added on-site. It is a powdered chemical admixture which complies to AS1478.1 (Chemical Admixture for Concrete) – Special purpose set-accelerating, high range water reducing, strength enhancing admixture.

It enhances the speed of cure in the early stages and can achieve a typical 28-day strength in 2 hours – more than 300 times faster than a conventional concrete. It reduces carbon emissions by a minimum of 20% per cubic metre of concrete compared to conventional concrete.
