MOCKINGBIRD LANE • DALLAS, TEXAS 75247-6913 • 214/647-6700 October 11, 1996 Austin Bridge & Road 11143 Goodnight Lane Dallas, Tx 75229 Attention: Mr. Gary Atwood RE: Austin Place - Coppell 8272 8274 Gentlemen: 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 mix 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, 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, Section 14 entitles a manufacturer to receive copies of all tests reports when strength of concrete is used as a basis for acceptance. Please contact us if you have any questions or require 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.

Keep rubber hose to absolute minimum length and plan pipe with as few 90 degree angles as possible. 3. Slumps and test cylinders should be taken at 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 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 pump ability at additional cost to the contractor. 6. TXI cannot control, and is therefore not responsible for excessive loss of entrained air when loss occurs due to pressure differentials created as a result of boom configuration or free fall discharge from end of hose. We are enclosing all available back data for the above referenced mix design. If the strength information is not available or is not sufficient, confirmation cylinders may have to be made by your testing laboratory.
