Eden Innovations has announced the successful completion of the independent lab testing of its EdenCrete enriched concrete being trialled at the Port of Savannah in Georgia.
The trial involves a section of concrete known as the 'runway' in the container terminal that is subject to very heavy loading and tyre abrasion from large gantry cranes. EdenCrete is a carbon-strengthened concrete additive that enhances a wide rage of performance characteristics of the concrete including compressive strength, flexural strength, abrasion resistance, reduced permeability, increased modulus of elasticity and reduced shrinkage, delivering stronger, toucher, more durable and longer lasting concrete.
The average compressive strength achieved in the independent lab tests by EdenCrete after 28 days was 10,010psi. This exceeds the required minimum strength of 5000psi.
Also of interest is the fact that the average compressive strength achieved after two days was 6780psi, after three days was 7810psi and after seven days was 8550psi.
Highly encouraging very early strength of the EdenCrete concrete was also obtained. The average compressive strength of the EdenCrete concrete at 28 hours after being poured, achieved 5720 psi, exceeding the minimum strength (4000psi) that is required for the repaired section to be re-opened for use, by 1720psi, or a very impressive 43%, and also exceeded by 15.2% the minimum 28 days strength of 5000psi.
This very early strength gain is significant operationally and commercially because the usual time before which a repaired section can be re-opened, is often around three to four days.
In this trial, EdenCrete was added to the concrete mix at 4.95 litres per cubic metre of concrete. The trial involves monitoring the ongoing performance of the EdenCrete concrete over the coming months. There is no set period for the trial, although Eden understands that the review of the performance is likely to undertaken over approximately three months.
The Port of Savannah is the third busiest US container port and the busiest on the nation's east coast. It is made up of two deep-water terminals and handles 20,000 container movements daily.
