DR9306-SP 950203February 03, 1995 TEXAS INDUSTRIES, INC. 1341 W. MOCKINGBIRD LANE · DALLAS, TEXAS 75247-6913 · (214) 647-6700 M.A. Vinson Construction Comp. P.O. Box 185577 Fort Worth, TX 7618] Attention Mr. Roy Hynds RE: Stream G-6 @ Bethel School Rd. 8272 Gentlemen: 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 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 design, when ordered by specified design identity, will meet or exceed the indicated design strength at a 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 the ACI 318 Building Code. TXI would like to be included on your mailing list to receive all test reports. ASTM C 94-86a Section 14.4 entitles a manufacturer to receive copies of all test reports when strength of concrete is used as a basis for acceptance. Contact us if you have any questions or require any additional information. Please notify TXI of approval of the proposed mix design prior to its use. To ensure that the proper mix design is 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, TEXAS INDUSTRIES, INC. Dana L.

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 @ 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, 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 pumpability at additional cost to the contractor. We are enclosing all available back up data for the above referenced mix design. If the strength information is not available or is not sufficient, conformation cylinders may have to be made by your testing laboratory. Date: 02/03/95 TEXAS INDUSTRIES, INC.
