Size bins for aggregates exposed to varying concentrations of microfibres

Microfibre abundance in aggregates were defined by counting microfibres observed in images of aggregates and then extrapolated per mm of the aggregate imaged. Microfiber abundance is measured per mm of aggregate size. Size bins of aggregates were calculated by first defining several size bins of aggregates from the range of aggregate size data measured during this study and then summing the abundance of aggregates which fell in to defined size classes.
