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
'1'~1.
TO ensure that the correct mix ~s delivered to your oro~ect,
please order by the mix design number which appears in the upper
left hand corner of the mix design.
ordered by specified design identity, and delivered by TXI, will
meet or exceed the indicated design strength at the designated
a~e when tested in accordance with the applicable and current
ASTM Standards C 31, C 39, C 78, C 172, C 293, applicable
provisions o~ C 94, and evaluated in accordance wi~n applicable
provisions of the ACI 318 Building Code.
TXI would like to be included on your mailin~ list to receive all
~¢~t r~port~. A~TM C 94 entitles a manufacturer to receive
copies of all test reports when strengtk of concrete is used as a
basis for acceptance.
Contact us if you have any questions or require any
information. Please notify TXI of approval of the proposed mix
design prior to ~ts use. ~Failure to notify us Drior 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 ~he above referenced project to be use~ Dy
