ABSTRACT: This paper aims to contribute to the
classification and specification of glass fiber reinforced concrete (GFRC)
and to deal with the question if structural glass fiber reinforced concrete as
a special kind of glass fiber reinforced concrete is suited for use in
load-bearing members. Despite excellent material properties, the use of glass
fibers in a concrete matrix is carried out so far only in non- structural
elements or as a modification for the prevention of shrinkage cracks. The aim
of re- search at the University of Applied Sciences in Leipzig is the use of
alkali-resistant macro glass fibers as concrete reinforcement in structural
elements as an alternative to steel fiber reinforcement. Slabs on ground, as
an example for structural members, provide a sensible application for the new
material because they can be casted as load bearing and non-load bearing and
are mostly made of steel fiber reinforced concrete. In the future, structural
glass fiber reinforced concrete shall provide a simple and visually appealing
alternative to conventional steel bar or steel fiber reinforced concrete. The
glass fibers can also be used in combination with conventional reinforcing
bars or mat reinforcements. Initial investigations have announced some
potential.
