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 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, 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 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.
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. 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,

PAVING & HANDWORK
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:' 4.00 inches
Air Entraining Agent: ASTM C-260
Admixture: ASTM C-494 Type A or D
MATERIAL QUANTITIES PER 1.0 CUBIC YARD AT S.S.D

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: 3.00 + 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,
equiyale~t 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.
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 pipeline
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.
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 insufficient, confirmation tests may have to be conducted by
your laboratory.
Strength of lightweight mix designs valid provided strength
specimens are cured in accordance with ASTM Test Method C 567, as
referenced in section 8.1 of ASTM Specification C 330.

COMMENTARY OF STATISTICAL EVALUATION OF CONCRETE DESIGN RESULTS

Strength: 3000 psi @ 28 Days
Paragraph 5.5 of ACI 318-95 prQvi~es 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 xn 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
= 3000
= 3754
F'cr = F'c
= 3000
= 3811
