Decommissioning particle sizing after a freeze-thaw laboratory based simulation of a permeable reactive barrier
Progress Code: completed Statement: Two samples were too wet during a first attempt of sieving. This material was left to dry for before completing the analysis. The impact of freeze-thaw cycling on a ZVI and inert medium was assessed using duplicated Darcy boxes subjected to 42 freeze-thaw cycles....

On completion of freeze-thaw cycling and solution flow (refer to Statham 2014), an additional series of assessments was conducted. The media from between the entry weir and the first sample port was removed in five approximately 400 g samples of increasing depth. This procedure was repeated between the last sample port and the exit weir. These samples were left to dry in a fume cabinet before duplicated particle sizing using a Endcotts minor sieve shaker.
