UPDATE- US Trials of Eden's Carbon Enriched Concrete Additive
• 22 % increase in Compressive Strength in Concrete after 21 days
• Second Trial with another US Concrete Manufacturer to Commence
Initial Results From First US Trials
Eden Energy Ltd ("Eden") is pleased to announce that the initial results, produced in laboratory tests
being conducted in conjunction with the first field trials in the United States of concrete made using
EdenCrete500, Eden's carbon-enriched concrete additive (see Eden's ASX Announcement dated 23
February 2015) , have produced encouraging results.
After adjusting for the additional water introduced into the mix with the addition of the EdenCrete500, the average normalised compressive strength of the concrete increased by 22% compared with a control cylinder of the same mix and age but which had no EdenCrete500 added to it.
These results were obtained when concrete cylinders were tested 21 days after the samples were made, using a moderate strength concrete mix provided by Metro Mix. Trials had been scheduled to occur at 7 days but these were not able to be carried out due to extreme weather conditions on the
day which prevented access to the test facility. Tests at 28 days and 56 days are yet to be undertaken.
Second US Trial by Independent Concrete Company to Commence
A further US trial is scheduled to commence this week in Colorado with a second US concrete
manufacturer that wishes to test the benefits that may be achieved by the addition of EdenCrete500 to its own particular concrete mixes. This concrete manufacturer has plants in several states of the US. The 56 day trial will be a laboratory trial which will involve periodic testing of concrete samples.
Background
EdenCrete500 ™, which in October 2014 won the Australian Civil Contractors Federation's 2014
Environment Award, is designed and formulated to deliver to concrete:
• Higher ultimate flexural (tensile) and compressive strengths;
• Improved abrasion resistance;
• Reduced tendency for corrosion of steel reinforcement;
• Improved concrete workability and effectiveness of water-reducer; and
• Reduced cracks from concrete shrinkage.
