Long term Deterioration of Fibre Reinforced Concrete Pipes

Long term Deterioration of Fibre Reinforced Concrete Pipes

Long term Deterioration of Fibre Reinforced Concrete Pipes

(OP)
I am interested in locating any references which address the long term performance of Fibre Reinforced Concrete pipes (with cellulose fibres) under adverse environmental conditions.

I would be very grateful to anyone who can direct me to references which discuss the longterm resistance to methane, hydrogen sulphide or similar possible liquid/gaseous products of garbage tips.

All responses will be very welcome.

RE: Long term Deterioration of Fibre Reinforced Concrete Pipes

I would also be interested in such information.  I recently had a 27 year old 18” diameter Glass-Fiber-Reinforced Thermosetting-Resin pressure pipe used as a sanitary sewer fail.  It appeared to me that the deterioration was from the outside in.  The fiberglass lining was still intact, but the aggregate and reinforcement was completely disintegrated.  Another interesting note is that the spigot end of the pipe which was surrounded by the adjoining pipe’s bell was not deteriorated at all; it was obvious that something in the pipe's exposure to the soil had caused this failure.  I have heard that the adhesive used to apply the mortar was water based, but I have not been able to confirm at this point.  I am currently researching soil conditions to determine possible affects.  One additional note is that it appeared that this pipe was put in on a trial basis because this is the only run of sewer in our jurisdiction made of such material.  The upstream and downstream runs of sewer are asbestos cement pipe and show no apparent signs of deterioration.
