Concretene is a graphene-enhanced admixture for concrete that delivers savings on cost and CO2 emissions. Laboratory tests and real-world projects have shown that Concretene offers significant benefits in compressive, tensile and flexural strength, as well as faster curing times and reduced permeability to water and salts. This enables comparable or greater performance to be achieved in concrete design mixes while using less cement. Concretene is added at the batching plant, like any other admixture, meaning no additional training or equipment is required. The resulting mixture is poured like any other concrete and the admixture can be used with >99% of existing concretes.
