Ann: Positive Results from Concrete and Coatings Testing, page-26

Andromeda Metals Limited (ASX Code: ADN, Andromeda, the Company) is pleased to announce further positive results from testwork undertaken in the newly identified applications of concrete and coatings.

Halloysite-Kaolin Testing for Concrete Applications

Halloysite-Kaolin Testing for Concrete ApplicationsFollowing receipt of some initial highly encouraging test results of halloysite-kaolin material in concrete and mine backfill applications, testing has continued and been expanded into a number of commercially important concrete application mix designs, and is continuing to deliver very positive results. A number of important handling and performance improvements of the concrete are being found with addition levels of only 1kg – 2kg/m3 of halloysite-kaolin, which Andromeda considers will make this potentially of genuine commercial interest for the existing domestic and global market. Testing will continue with official Australian Concrete Standards Certification anticipated in late November 2020.

The concrete industry represents a new and very significant domestic and global market opportunity for halloysite-kaolin where results to date indicate that it provides genuine benefits. Most importantly, at an addition level that makes it commercially attractive to use, it potentially represents a much higher value to Andromeda than other applications. Once the reduced amount of required processing is factored in, the opportunity becomes extremely compelling.

Concrete application areas under testing which are currently all showing positive results include; self-consolidating concrete, shotcrete, pool mix and deep foundation pilings. As a result, a large-scale underground shotcrete trial is planned to obtain real-life performance data on the benefits from halloysite-kaolin addition.
