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 test reports when strength of concrete is used as a basis for acceptance. Please contact us if you have any questions or require any 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.

The required average compressive strength has been calculated using a standard deviation calculated in accordance with ACI 318 -89 Section 5.3.1.1 or Section 5.3.1.2 and is the larger value of these calculations f' = f' + 1.34(SD) = 3000 + 1.34(00517) 3693 f' = f' + 2.33(SD) - 500 = 3000 + 2.33(00517) - 500 = 3705 SUMMARY OF STATISTICAL ANALYSIS 28 Day Test Data Numberof Tests .......................... 30 Maximum Value ............................ 5295 psi Minimum Value ............................ 3410 psi Range......... ......................... 1885 psi Average Strength ......................... 4247 psi Standard Deviation..... ................ 517 psi Required Average Strength to satisfy minimum probability conditions of ACI 318 -89 Section 5.3.2.1 ............... 3705 psi Design excess beyond code requirements.. 542 psi MIX # 8272 5.00SK ADMIX /AEA 1 "CS 3000 PSI @ 28 Days SLIP FORM PAVING Maximum Coarse Aggregate Size: ASTM C 33 1"- #4 Crushed Stone Maximum Water /Cement Ratio: 6.00 gal /sk .531 lb /lb Minimum Cement Content per Cubic Yard: 5.00 sacks Maximum Placement Slump: 3.0 inches Admixture ASTM C -494: Type A or D Air Entraining Agent ASTM C -260: 3% - 6% MATERIAL QUANTITIES PER 1 CUBIC YARD AT S.S.D. 470 lbs. or 5.00 sacks ASTM C 150 Type I Cement 1840 lbs.

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. 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 of concrete from end of hose. 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.
