Table 1 - Results for Testing using the AEISG Code of Practice
Table 2 - Results for Testing using the QMR Reactive Ground Test
Prior to testing as per the AEISG Code of Practice each sample was assessed for reactivity risk based on pH, carbonate and amount of reactive sulphide using the QMR Reactive Ground Test (refer to Table 1 and Table 2 for results of both tests). All samples were alkaline and contained carbonates which reduces the risk of reactivity. Two samples contained sulpide levels of trace and 0.6% which is below the level to be reactive in alkaline conditions when tested as per the AEISG Code of Practice Reactivity Screening..
Conclusion:
No samples were found to be reactive when tested as per the AEISG Code of Practice and the QMR Reactive Ground Test.
