P.O.Box 15448 Fort Worth,TX. 76119 Attn:Mr.Bill Hurst RE: Ridgecrest Estates-Coppell Mix Code Numbers 8272,8273SF,8274 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-mixed 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 left hand corner of the mix design. TXI certifies that the above mix designs,when ordered by specified design identity,and delivered by TXI,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 the ACI building code. TXI would like to be included on your mailing list to receive all test reports.ASTM C 94 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. Failure to notify us prior 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 the above referenced project to be used by the person ordering the concrete for this job. The information contained in this submittal is confidential and the exclusive property of TXI.It cannot be copied,duplicated or disclosed to third parties without the expressed written consent of TXI. Sincerely, TXI Operations,LP Victor H.Villarreal Pumping Notes: 1. 5"minimum diameter lines with no reduction to smaller lines. 2. Keep rubber hose to absolute minimum length and plan pipe with as few 90 degree angles as possible. 3. Samples for slump and strength tests 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 is recommended 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,mix design modifications may be required to assure strength and pumpability at additional cost to the contractor. 6. TXI cannot control,and is therefore not responsible for excessive loss of entrained air content when loss occurs as a result of boom configuration or free fall discharge from hose. To ensure minimum air loss when pumping,maintain a continuous flow of concrete through the entire length of pipe and do not subject concrete to free fall. 7. The term"pumpable concrete"refers to concrete which is capable of being transported through an apparatus which forces concrete to the placing position through a pipeline or hose as long as the recommendations indicated above are followed. The term"pumpable concrete"does not relate to concrete proportioned in a particular manner or containing a specific type of product. Strength of lightweight mix designs valid provided strength specimens are air cured in accordance with ASTM Test Method C 567-05,section 7.3 except as modified in section 8.1,alternative method, ASTM Specification C 330-04. Unless otherwise indicated, when the concrete temperature at point of placement exceeds 90 degrees Fahrenheit,TXI will guarantee the strength performance of the mix design(s)herein submitted up to a maximum placement temperature of 100 degrees Fahrenheit using an ASTM C 494 Type D retarding water-reducer,as long as the concrete is placed within 75 minutes from batch time.Unless otherwise indicated,strength of plain concrete guaranteed up to a maximum placement temperature of 85 degrees Fahrenheit. We are enclosing all available back up data for the referenced mix design(s). If the strength information is not available,or is insufficient,confirmation tests may have to be conducted by your lahnratnry le) 13.14 West Mockingbird Lane DaIt s.Texas 75217 • 972.617.6700 txi.cam Customer: Conatser Construction,Inc.
