The attached concrete mix design utilizing the appropriate ASTM
C-33 or ASTM C-330 aggregate is 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 ~roject,
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 design, 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 ACI 318 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 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.
Sincerely,
Texas Industri~~.~,..~.~

Maximum Coarse Aggregate: 1" - #4 CRUSHED STONE
Maximum Water/Cement Ratio: 6.20 gal/sack or 0.549 lbs/lb
Cement/Cementitious Content: 5.00 sacks (per cubic yard)
Maximum Placement Slump: 3.00 inches
Air Entraining Agent: ASTM C-260

MATERIAL QUANTITIES PER 1.0 CUBIC YARD AT S.S.D
470 lbs. ASTM C 150 TYPE I CEMENT
1840 lbs. 1" - #4 CRUSHED STONE
1352 lbs. CONCRETE SAND
258 lbs. or 31.0 Gallons of Water
2.0 to 4.0 oz/cwt of ASTM C-494 Type A
Specified Air Content: 3.0% - 6.0%
Placement Slump: 2.00 + or - 1.00 inches
PUMPING NOTES / 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. Samples for slump and strength tests 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.
6. TXI cannot control, and is therefore not responsible for
excessive loss of entrained air content when loss occurs as
a result of boom configuration or free fall discharge from
hose. To ensure minimum air loss when pumping, maintain a
continuous flow of concrete through the entire length of
pipe and do not subject concrete to free fall.
We are enclosing all available back up data for the referenced
mix design(s). If the strength information is not available, or
is insufficient, confirmation tests may have to be conducted by
your 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( 564.7)
= 3757
F'cr = F'c + 2.33(SD) - 500
= 3000 + 2.33( 564.7) - 500
= 3816
