Abstract
A concrete structure is lined with a statically self-supporting glass shell composed of shell segments which are themselves joined together by sealing strips. In a pipe embodiment of the invention, the shell segments form a ring spaced from the concrete body with the spacing being filled by a backfill mass so that a compressive prestress is provided to the arch shape. When used in a container, the shell may be a laminate of two or more glass layers bonded full surface together.
