Specimen designation
The specimens in Tables 1 and 5–8 were labeled as follows:
Each label started with letter C and letters UC for confined and
unconfined specimens, respectively, which was followed by a dash.
In specimens that contained no internal steel fibers, the letters ‘UR’
were used after the dash to denote ‘unreinforced’. In specimens
that contained steel fibers, the dash was followed by a subsequent
letter (i.e., either H (for hooked end) or C (for crimped)) that was
used to indicate the shape of the steel fiber. The following letters
V and A were used to represent the test parameters, namely, the
steel fiber volume fraction (in percent) and steel fiber aspect ratio,
respectively. Each of these letters was followed by a number that
was used to specify the value of the given parameter. In specimens
manufactured with SIFCON mixes, the abbreviation ‘SIF’ was added
to the end of the specimen designation. Finally, the last number in
the specimen designation (i.e., 1, 2 or 3) was used to distinguish
three nominally identical specimens. For example, C-CV2.5A44-1
is the first of the three identical SFRHSCFFT specimens that were
reinforced by crimped steel fibers with at an aspect ratio of 44,
which were added to the mix at a fiber volume fraction of 2.5%.
