The following is the concrete mix design used in the laboratory
to cast concrete specimens used for the shear and bond tests as
shown in our report dated March 7, 1985.

PROCEDURE USED:
A. Shear
Tests
Specimens were cast in 6" x 6" x 20" beam molds and
when sufficiently aged were tested in shear.
B. Bond
Tests
In Test No. 1, No. 5 rebars were imbedded in concrete
and when sufficiently aged were tested in
tension.
Specimens for Test No. 2 were Cast in dimensions according to ASTM C-321-64, (Bond Strength of ChemicalResistant Mortar) and when sufficiently aged were tested on a special test head as shown in Figure 4 of ASTM C-321.
NOTE:When evaluating the test results, consideration should be given to the comparison between small size laboratory specimens and large concrete field members. Also, the laboratory specimens received full coats of slurry and powder over entire surfaces. It is possible that the laboratory specimens were subjected to more stringent procedures than may be found in the field.
