Following encouraging results from an earlier trial, a second EdenCrete trial involving two larger sections of concrete pavement was undertaken in in
The evaluation was reported to Eden in a letter dated
During the inspection, I noted that the EdenCrete concrete had performed exceptionally well over the last three years. This was particularly remarkable given the very high volume of vehicle use and associated surface abrasion coupled with the heavy and often repeated magnesium chloride applications. The test sections looked great. I observed no scaling or cracking in the EdenCrete sections, while the reference sections, with no EdenCrete, were exhibiting load and plastic shrinkage cracking and scaling.
OAM1 has included EdenCrete through statement in the specifications that admixtures not listed may be used with approval of the product manager. We will continue to use the product in areas where a high level of reliability is required. We are extremely pleased with the EdenCrete product and look forward to continuing our evaluation of the product.'
This long-term assessment by a government department after a 3-year field trial, conducted under very tough conditions, is of major importance to the future marketing of EdenCrete across all parts of the US, as well as in any other countries, that are subject to snow and freezing winter conditions and where de-icing salts and road chemicals are commonly used.
EdenCrete is already in use or being trialled by a number of other US government agencies, including the

This study provides an independent technical assessment of some of the other benefits delivered by EdenCrete in this field trial. It analysed the comparative performance of a standard concrete mix, and two other similar mixes but with EdenCrete added at 2 gallons/ cubic yard of concrete and at 3 gallons/ cubic yard of concrete respectively. It measured and compared changes in the three mixes in respect to compressive strength at 7 days and 28 days, as well as slump that was measured at the time of conducting the tests. In all the tests, the EdenCrete enriched concrete outperformed the standard concrete mix.

BACKGROUND
EdenCrete is Eden's 100% owned, proprietary carbon-strengthened concrete additive that enhances a wide range of performance characteristics of the concrete including compressive strength, flexural strength, tensile strength, abrasion resistance, reduced permeability, increased modulus of elasticity, and reduced shrinkage, delivering stronger, tougher, more durable and longer lasting concrete.
EdenCrete delivers not only a wide range of performance benefits in concrete, but also delivers economic advantages through many ways, including greater durability and service life for the concrete. Additionally, in applications where fresh concrete has to be pumped under pressure, including in shotcrete or pumping of fresh concrete up high -rise projects, it greatly reduces the friction enabling the required pumping pressure to be reduced, resulting in less wear on the pumps, and safer working conditions due to reduced nozzle pressure being required, which in turn results in cost savings through less wasted concrete resulting from reduced re-bound in the case of shotcrete applications.
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, freeze/thaw weather conditions and/or high levels of added salt. Additionally, it has potential for use in most other concrete applications including high-rise building construction, marine and coastal applications, water storage and pipelines, hardstand areas, warehouses, shotcrete applications and prestressed and pre-cast concrete structures and products.
