Coppell, Texas
HBC;q'erracon Report No. 94051190.0002
Dear Mr. Sorrels:
We nave reviewed the concrete mix design, (TXI Mix No. 8206) submitted by McFadden &
Miller, Inc., for firelane and general pavement use at the above referenced proiect. Our
comments regarding the mix are documented in the attached report.
Thank you for the oppodunity to provide this service, Please feel free to call if I may
answer any questions or assist in any way.
Yours truly,

Comments:
This mix contains 60 sacks total cementitious material; 4.8 sacks (451 lbs.) of Type I/il
cement and 113 lbs. of ~'t~ (2~ bY vofl, lmef; 1" crushed stone for the coarse
aggregate; ASTM C 494 water reducing admixture, and ASTM C 260 air entraining agent;
and is designed for a maximum 5" slump at the point of deposit . it is designed for
pavement use. The submittal did not provide: the source of Cement and Fly Ash,
maximum elapsed time before discharge after introduction of water and cement, and
minimum concrete temperature.
Conclusion:
The cement/fly ash ratio appears to be in compliance with the current edition of NCTCOG
Standard Specifications. The strength requirement meets the minimum criteria per ACI
specifications and project specifications. Terracon feels that this submitted mix should be
adequate for pavement use on this project, as long as the maximum slump is not
exceeded, the proper placement and curing temperatures are met and batoh to placement
times are not exceeded. Final acceptance of this mix must be by the civil enqineer.

The attached concrete mix design utilizmg the appropriate ASTM C-33 or ASTM C-330
aggregate is proposed fi)~ t~se on the above referenced project for ready-nmxed concrete to
be £uudsh,.:,l b.~ llX].
'£XI certifies that the above max design~ when ordered by specified design identity, and
delivered by TXI, w-ill meet or exceed the mdicated design siren=mil at the designated age
when tested m accordance nth the applicable and current ASTM Standards C 3 l, C 39,
C 78, C 172, C 293, applicable pro~Ssions of C 94, and evaluated in accordance with
applicable provasmns of the AC! 318 Building Code.
TYd would like to be mcluded on your maihng li~ to receive all test reports. ASTM C 94
entitles a manttfacturer to receive copies of all test reports when strength of concrete
used as a basis for acceptance.
Contact us if you ha~e any quest/ohs or require any additional re.formation. Please nofif3'
TXI of approval of the proposed mix desibm prior to its use. Failure lo notify us prior to
first placemenl shall constitute acceptmace. To ensure that the proper nmx design is
ordered, please send a copy of th.is letter, aRer approval, to the above referenced project
to be used by the person orderLng the concrete for this job.

GENERAL NOTES
Pumping Notes:
5" rniniumm diameler lines with no reduction to smaller lines.
2 Keep robber hose to absolute Wantmtau length and plan pipe with as few 90
degree angles as posqfl)le
3 Samples fo~ slump and strength tests ~hould be taken at &scha.rge end of ho~e
lot strength guarantee to be valid
4. To prime pump lines, a mmimmn of 8.0 sack grout is recommended for
lubrication tn the ca~e of strength concrete,
equivalent strength grout should be u~ed if the grout remains m the placement.
5. Pump mixes are based on minimum cement content pumped at
ground level As pmnp line increases in length or height
m~dfar layou~ configttration changes, mix design moclifieafions may be
required to assure strength and pumpability at additional cost to the contractor.
6. TX] cannot control, and is therefore not responsible for excessive loss of
entrained air content when toss occurs as a result of boom confi~tion or
free fall discharge ISom hose To ensure minimum air loss when pumping,
mainta~n a continuous flow of concrete through the enlire length of pipe and
do no~ subject concrete to free fall
The term "pnmpable concrete" refers to concrete w~fich is capable of being
uansported fl~ro ~ugh an apparatus which force~ concrete to the placing position
fluough a p~peline or hose as long as thc recommendations indicated above are
fotlo~a'ed. Ihe {erin "pumpable concrete" does not relate to concrete
propoifioned in a pm-titular- mamaer or cemmning a specific type of product
Stren~ of lightweight roux designs valid provided strength specimens use a.u :ured
m accordance with ASTM Test Method C 567-01, as referegced in section 8.1 of
ASTM Specification C 330.
Unles~ otherwise inflicated, when the concrete temperature at point of placement
exceeds 90 degrees Pa.hrenbeit, TXq ,,rill gum'antee the strength performance of the
nn~c design(9 herein submitted up to a maximum placement temperature of 100
degrees Fat~rcnheit using aa ASTM C 494 lype D retarding water-reduce~, as tong
as the concrete is placed witlUn 75 minutes ih'om batch tithe. Unless otherwise
indicated, strength of piton concrete guaranteed up to a maximum placement
~emperamre of 85 de~ees Fahrenheit.
We are enclosing at1 available back up ~ata for thc referenced mix design(s). If the
strength in'formauon ts not available, or is ms~ff~cient, confirmation tests may lmve
to be conducted by 5'our laboratory
