||Subcommittee on Durability of Concrete Pipe and Manholes Proposed
Interested parties are invited to an organizational meeting, May 7, 1:00 p.m., at the Omni Austin
Hotel, Austin, Texas, where the scope and activities of a proposed
ASTM Subcommittee on Durability of Concrete Pipe and Manholes
will be discussed by members of ASTM Committee C13 on Concrete Pipe.
The new proposed subcommittee on durability would develop new
test methods for accelerated corrosion resistance testing of concrete
pipe, explained C13 member Jeff Enyart, vice president of product
development, ISG Resources, Texas, who will lead the organizational
meeting. In addition, the committee would develop standard guidelines
to provide direction to users regarding the various corrosion-resistive
options available and guidelines for use in predicting the service
life of these various materials.
Participation and input is sought from interested agencies and
engineers, especially those who use similar test methods.
The scope of the proposed subcommittee is to develop methods
of testing, specifications, definitions, practices, guidelines
and to stimulate research relating to the durability and performance
of concrete pipe materials, components and combined assemblies
that is subjected to various environments. These objectives will
be implemented by the development and coordination of standards
relating to nomenclature, standard conditions, and methods associated
with the exposure to specific environments and accelerated or
service testing of such materials, components and combined assemblies.
These efforts will benefit users and producers by developing
standard test methods that will allow groups to make meaningful
comparison of the tests by various agencies and of various materials,
added Enyart, a civil engineer who develops enhanced pozzolan
technology for concrete products at ISG. Durability of concrete
pipe and manholes can be a concern in certain applications, particularly
sanitary sewer applications, where corrosive conditions may exist.
There are a number of companies either developing or supplying
various products that provide corrosion protection for concrete
pipe used in sanitary sewer or other potentially corrosive environments,
he continued. In addition, there are a number of groups that
are using a variety of test protocols to simulate accelerated
testing of concrete products in corrosive environments. Each agency/engineer/manufacturer
uses different test methods that they feel has certain advantages
in predicting the long-term performance of materials.
The committee shall establish liaison with other ASTM technical
committees with related interests. Where appropriate, the committee
will also assure that its standards are harmonized with related
