Perth based-company Eden Innovations has made steady progress with its EdenCrete products in the USA, but it still awaits regulatory approval for local use.

Aus concrete innovation making gains
EdenCrete is being used on the Central 70 project on the Interstate Highway I-70 in Denver, Colorado.

EdenCrete is a carbon-strengthened concrete additive that enhances concrete by giving it more compressive and flexural strength and is especially useful when added to concrete that is applied as high-pressure shotcrete.

Eden Innovations created EdenCrete admixture using ‘carbon nanotubes’ – an additive that fills in the gaps that form between wet cement particles and can cause structural weakness in non-treated conctrete - way back in 2010.

In applications where fresh concrete must be pumped under pressure up to high-rise construction projects the added EdenCrete also reduces friction, resulting in less wear on the pumps; reduced nozzle pressure where the concrete is sprayed; and considerably less concrete is wasted due to a reduction in the rebound of fresh concrete falling of the wall face.

Its applications include re-inforcement and buttressing of bridge piers and ground-anchored retaining walls; enhancing road-cut stability to inhibit rock-slides; the construction of vertical concrete surfaces and in the constrution of swimming pools.

EdenCrete  is being used on the Central 70 project on the Interstate Highway I-70 in Denver, Colorado; a project that commenced in late 2018 and is still ongoing.

The product is being used to assist in both buttressing and ground-anchored retaining walls along the 16 kilometres of highway re-construction, that is expected to require between 4587 and 7645 cubic metres of shotcrete.

One of the primary target markets for EdenCrete is improving the performance of concrete used in the construction and maintenance of concrete roads, bridges and other infrastructure, particularly where it is subject to heavy wear.

A decision on its use in Australia is expected to be made by the end of 2020.
