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-mixed concrete
to be furnished by TXI.
TXI certifies that the above mix designs, when ordered by specified design identity, and
delivered by TXI, will meet or exceed the indicated design strength at the designated age
when tested in accordance with the applicable and current ASTM Standard~ C 3 I, C 39,
C 78, C 172, C 293, applicable provisions of C 94, and evaluated in accordance with
applicable provisions of the ACI Building Code.
TXI would like to be included on your mailing list to receive all test reports. ASTM C 94
entitles a manufacturer to receive copies of all test reports when strength of concrete is
used as a basis for acceptance.
Contact us if you have any questions or require any additional information. Please not/fy
TXI of approval of the proposed mix design prior to its use. Failure to notify us prior to
first placement shall constitute acceptance. To ensure that the proper mix design is
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.
The information contained in this submittal is confidential and the exclusive property of
TXI. It cannot be copied, duplicated or disclosed t~ird parties without the expressed
written fonsent of TXI.

COMMENTARY OF STATISTICAL EVALUATION OF CONCRETE DESIGN RESULTS
Mix Num:8273
Strength: 4000 psi @ 28 Days
Paragraph 5.5 of ACI 318-02 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 strength has been calculated using a
standard deviation calculated in accordance with ACI 318-02
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)
= 4000 + 1.34( 401 )
= 4537
F'cr = F'c + 2.33(SD) 500
= 4000 + 2.33{ 401) - 500
= 4435
