The formation of organic acids by
fermentation and/or the addition of acids
to wet bulk storage piles creates
corrosion problems. Slabs under wet bulk
storage piles made of concrete will be
subject to corrosion and will need to be
resurfaced rather frequently. Asphalt
surfacing has been proposed, but the
danger is that particles and fragments of
asphalt may enter the pulp mill which is
decidedly detrimental. Epoxy resin and
other plastic coatings can be used to
protect the concrete but are expensive.
