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.
To ensure that the correct mix is delivered to your project, please order by thc mix design
number which appears in the upper left hand comer of the mix design.
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 Standards C 31, C 39,
C 78, C 172, C 293, applicable provisions of C 94, and evaluated in accordance with
applicable provisions of the AC1 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 notify
TXI of approval of the proposed mix design prior to its use. Failure to notify us prior m
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,
Sincerely,
TX v rio

PUMPING NOTES:
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. Samples for slump and strength tests 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 is recommended for
lubrication. In the case of strength concrete,
eqnlvalant strength grout should be used if the groin 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, mix design modifications may be
required to assure strength and pumpability at additional cost to the contractor.
6. TXI cannot control, and is therefore not responsible for excessive loss of
entrained air content when loss occu~'s as a result o£boom configuration or
free fall discharge from hose. To ensure minimum air loss when pumping,
maintain a continuous flow of concrete through tee entire length of pipe and
do not subject concrete to free fall.
7. The term "pumpable concrete" refers to concrete which is capable of being
transported through an apparatus which forces concrete to the placing position
through a plpeline or hose as long as the recommendations indicated above are
followed. The term 'pumpable concrete" does not relate to concrete
proportioned in a particular manner or containing a specific type of product.
S~ength of lightweight mix designs valid provided strength specimens are air cured
in accordance with ASTM Test Method C 567-01, as referenced in section 8.1 of
ASTM Specification C 330.
Unless otherwise indicated, when the concrete temperature at point of placement
exceeds 90 degrees Fahrenheit, TXI will guarantee the strength performance of the
mix design(s) herein submitted up to a maximum placement temperature of 100
degrees Fahrenheit using an ASTM C 494 Type D retarding water-reducer, as long
as the concrete is placed within 75 minutes from batch time. Unless otherwise
indicated, strength of plain concrete guaranteed up to a maximum placement
temperature of 85 degrees Fahrenheit.
We are enclosing all available back up data for the referenced mix design(s). If the
strength information is not available, or is insufficiem, confirmation tests may have
to be conducted by your laboratory.

COMMENTARY OF STATISTICAL EVALUAT..ION OF CONCRETE DESI~ RESULTS
Mix Num: 8203
Strength: 3000 psi @ 28 Da~S
Parag!aph 5.5 of ACI 318-99 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:
30 or more test results are available and average ef
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( 533)
= 3714
F'cr = F'c + 2.33(SD) 500
= 3000 + 2.33( 533) - 500
