Attention Mr. Mike Ducote'
RE: Round Oak Estates - Coppell

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 94-86a Section 14.4 entitles a manufacturer to receive
copies of all test reports when strength of concrete is used as a basis
for acceptance.
Please contact us if you have any questions or require any additional
information. Please notify TXI of approval of the proposed mix designs
prior to their use. 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 @ 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 the 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 pumpability at additional cost
to the contractor.
We are enclosing all available back up data for the above referenced mix
design. If the strength information iS not available or is not
sufficient, conformation cylinders may have to be made by your testing
laboratory.

COMMENTARY OF STATISTICAL EVALUATION OF CONCRETE DESIGN RESULTS
Mix No. E8272
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'_r) 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' = f' + 1.34(SD) cr c
= 3000 + 1.34(00520)
: 3697
cr
= f' + 2.33(SD) - 500
C
= 3000 + 2.33(00520) - 500
= 3712
