**************************************************************************
NOTE: Consult the appropriate DM to fill in the
blanks.
**************************************************************************
Mixture proportions and test data from prior experience within [_____]
years, if available, may be submitted for approval. If test data from
experience are not available or accepted, specimens shall be made and
tested from mixtures having three or more different proportions. The
recommended mixture proportions, sources of materials, and all test results
shall be submitted for acceptance. [Mixture proportions for
nonfiber-reinforced shotcrete shall be selected on the basis of compressive
strength tests of cores obtained from test panels fabricated in accordance
with ASTM C 1140 and having minimum dimensions of 750 by 750 by 100 mm 30
by 30 by 4 inches. Cores shall be continuously moist cured until testing
at [_____] days age. For mixture acceptance purposes, the average
compressive strength of at least three cores shall be at least equal to 1.2
times the required compressive strength specified in paragraph COMPRESSIVE
STRENGTH.] [Mixture proportions for fiber-reinforced shotcrete shall be
