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). The pH of the samples was low which increases the risk of reactivity. Two samples contained sulpide levels of >4. % and one of these samples contain 16% coal which inhibits the reaction.
Conclusion:
The following samples are reactive as per the AEISG Code of practice:
5324C_RG12
5340C_RG04
The following samples are marginal as per the AEISG Code of practice:
5324C_RG16
5340C_RG01
5340C_RG02
5340C_RG12
All other samples tested as not reactive.
