The am~hed concrete mix design utilizing the appropriate ASTM C-33 or ASTM C-330
aggregate is proposed for u~e on thc above ret~enced projecl for ready-mLxed concrete to
be fitrni~hed by TXI.
To ensure that the correct mix is delivered to your project, plea.~ order by uh¢ mix design
number which appears in the upper left hand comer of the mLx design.
TXI certifies the: the abo'~e mix design, when ordered by specified design identity, and
delivered by TXI, will meet ot exceed thc indicazed design sucngth at the designated age
when taslcd in a~cordanc¢ with thc applicable and currcn! ASTM Standards C 31, C 39,
C 78, C 172, C 293, applicable provisions of C 94, and ¢¥aluatcd in ac¢or_,t~-¢¢ wi~
applicable provisions of thc ACI 31 $ Building Code.
TXI would like to be included on your mailiag list to r¢c¢iYe all tcsl r~ports. ASTlvi C 9,1
amities a manufac~rcr to receive copies of all tos! tvporta when strength of concrc:¢ is
used aa a basis for acceptance.
Contact us id' you have any questions or require any additional information. Please notify
TXI of approval of thc proposed mix design prior to its use. Failure to notify us prior to
ftrs~ placement shall constitute acceptance. To ensuxe ~ha! the proper mix design is
ordered, please send a copy of this letter, attcr approval, to the abow referenced project to
be used by the person ordering the concrete for this job.

4. To prime pump lines, a minimum of 8.0 sack grout is recommended for
lubrication, In r. he case ofstrenknh concrete,

Pump mixes are based on minimum cement conlcnt pumped at

6. TXI carmot con~'ol, and is therefore not rcsponsible for excessive loss of
~ltraingd sir content when tos-~ occurs as a result of boom configuration or

m~intsln a continuous flow of concrel¢ through ~¢ entire length of pipe and
do not subject concrete to free faU.
