Dynastone® Generation 2
Dynastone® is a corrosion resistant cementitious material
that is able to resist attack from sulfuric acid generated in the sanitary
sewer environment. Dynastone® utilizes a chemically activated high volume fly
ash mixture that dramatically improves the durability of the concrete
pipe. The fly ash is an integral part of the Dynastone® technology. It acts as
a replacement of a major component of the Portland cement commonly used in
pre-cast concrete pipe.
Dynastone® offers several advantages over current solutions
to the corrosion problem. Dynastone® is much more economical than lining and
more economical than coatings. The entire structure is made of an acid
resistant, strong material and therefore there is no risk that an inferior
quality application of a liner negating the acid resistance of the rest of the
structure. Dynastone® is available in both dry cast and wet cast formulations
that can be manufactured with any existing equipment in any size. Aside from
the requirement of an ash silo, there are no special installation requirements
and welding of the joints is not necessary.
