Vill~rreal Manager - Q~A./O.C, 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 cl~grce allgles as possible. 3. 'Samplcs for simp and s~rength tests should be taken et discharge end of hose for str~-ngth guarantee to be valid. 4. To prime pump lines, a minimum of g,0 sack grout is r~commande.~l for lubrication. In the case of strength concrete, equivalent strength grout should be used if thc grout remains in the placement- 5. Pump mixes axe based on minimum cement content pumped at grouaxd level. As pump line increases in length or height and/or layout configuration changes, mix design modifications may be required to assu~o. ~hength 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 occuxs as a result of boom configuration or f~ce fall discharge from hose. To ensure minimum air loss when pumping, maintain a continuous flow of concrete through the cnti~c length ofplpe and do not subject concrete to free fall. 7. The term 'pumpable concrete" refers to concrete wklch is capable of being tmn.~portcd tkreugh an apparatus which forces concret~ to thc placing position through a pipeline or hose as long as thc recommendations indicated above a~ followed. The term "pumpable concrete" does not relate to concrete proportioned in a particular manner or containing a specific type ofproduet. Strength of lightweight mix designs valid provided strength specimens ar~ air cured in accordance with ASTM Test Method C 567-01, as referenced in section $.1 of ASTM Specification C 330. Unl~as otherwise indicated, when thc concrete temperature at point of placement exceeds 90 degrees Fahrenheit, TXI will guarantee the strength performance of thc mix design(s) h~r~in submitted up to a maximum placement temperature of 100 degrees Fahrenheit using an ASTM C 494 Type D retarding water-reducer, as long as thc concrete is placed within 75 minutes from batetl lime. Ull]ess otherwise indicated, strength of plain concrete guaranteed up to a maximum placement tcml~Tatur~ of 85 degrees Fahrenheit, We are enclosing all available back'up data for thc referenced mix design(s). If the strength information is not available, or is insufficient, confirmation tests may have to be conducted by your laboratox3n TXI I'ROFP.
