Decommissioning particle sizing after a freeze-thaw laboratory based simulation of a permeable reactive barrier
The impact of freeze-thaw cycling on a ZVI and inert medium was assessed using duplicated Darcy boxes subjected to 42 freeze-thaw cycles. This dataset consists of particle sizing during the decommissioning process of the experiment. Two custom built Perspex Darcy boxes of bed dimensions: length 362...
