Gentlemen:
The attached concrete mix designs utilizing the appropriate ASTM C-33 or ASTM
C-330 aggregate are proposed for use on the above referenced project for ready mix
concrete to be furnished by TXI.
To ensure that the correct mix is delivered to your project, please order by the mix design
number which appears in the upper left hand corner of the mix design.
Texas Industries certifies that the above mix designs, when ordered by specified design
identity, will meet or exceed the indicated design strength at the designated age when
tested in accordance with the applicable and current ASTM Standards C 31, C 39, C 78,
C 172, C 293, applicable provisions of C 94, and evaluated in accordance with applicable
provisions of ACI Building Code.
TXI would like to be included on your mailing list to receive all test reports. ASTM C 94,
Section 14 entitles a manufacturer to receive copies of all tests reports when strength of
concrete is used as a basis for acceptance.
Please contact us if you have any questions or require additional information. Please
notify TXI of approval of the proposed mix designs prior to their use. Failure to notify us
prior to first placement shall constitute acceptance. To ensure that the proper mix designs
are ordered please send a copy of this letter, after approval, to the above referenced
project to be used by the person ordering the concrete for this job.
Sincerely;
TEXAS INDUSTRIES, INC.

PUMPING RECOMMENDATIONS
1. 5" minimum diameter lines with no reduction to smaller lines.
2. Keep rubber hose to absolute minimum length and plan pipe with as few 90
degree angles as possible.
3. Slumps and test cylinders should be taken at discharge end of hose for
strength guarantee to be valid.
4. To prime pump lines, a minimum of 8.0 sack grout should be used for
lubrication. In case of strength concrete, equivalent strength grout should be
used if the grout remains in the placement.
5. Pump mixes are based on minimum cement content pumped at ground level.
As pump line increases in length or height and/or layout configuration
changes, additional cement may be required to assure strength and
pump ability at additional cost to the contractor.
6. TXI cannot control, and is therefore not responsible for excessive loss of
entrained air when loss occurs due to pressure differentials created as a result
of boom configuration or free fall discharge from end of hose.
We are enclosing all available back data for the above referenced mix design. If the
strength information is not available or is not sufficient, confirmation cylinders may have
to be made by your testing laboratory.

COMMENTARY OF STATISTICAL EVALUATION OF CONCRETE DESIGN RESULTS
Mix Num: 8272 Strength: 3000 psi @ 28 Days
Paragraph 5.5 of ACI 318-89 provides that as data becomes
available during construction, the amount by which (F'cr) must
exceed the specified value of (F'c) may be reduced, provided:
(a) 30 or more test results are available and average of
test results exceeds that required by Section 5.3.2.1,
using a standard deviation calculated in accordance
with Section 5.3.1.1, or
(b) 15 to 29 test results are available and average of test
results exceeds that required by Section 5.3.2.1, using
a standard deviation calculated in accordance with
Section 5.3.1.2.
The required average compressive strength has been calculated
using a standard deviation calculated in accordance with
ACI 318-89 Section 5.3.1.1 or Section 5.3.1.2 and is the larger
value of these calculations:
F'cr = F'c + 1.34(SD)
= 3000 + 1.34(412.4)
= 3553
F'cr = F'c + 2.33(SD) - 500
= 3000 + 2.33(412.4) - 500
= 3461
