To ensure that the correct mix is delivered to yo~r ~roject, please order by the mix design number which appears mn the upper left hand corner of'the mix design. Texas Industries certifies that the above mix de'signs, when ordered by specifie~ d~slgn ±dentiuy, and delivereu Dy TXI, will meet.or exceed the zndzcated design strength at the.designated age when testc~ in accordance with the applicable.and current ASTM Standards C 31, C 39, C 78, C 172, C 293, applicable prov%s~on~ of C 94, and evaluated in accordance wzth applicable .provzszons of 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 cf all test reports when strength of concrete is used as a basis for acceptance. Please contact us if you have any .q~.estions or require any additional infommation. Pi==~ nut~£y TXI of approval of the proposed mix designs prior to their use. Failure to notify us prior to first placement ohull constitute acceptance. To ensure that the proper mix designs are ordered, please send a copy of ~h~ l~tt~r, aft. a~ approval, to the above referenced ~roject to be used by the person ordering the concrete for th~s ]ob.

To prime DumP.lin~a, a minimum of 8.0 sack grout sho~ld hm used for lubrication. In the case of strength concrete, equivalent strength grout should be used if the qrout remains in the placement. 5. Pump mixes are based on minimum cement content pumped at ground level. AS pump line increases in.l~ngth or height and/or layout configuration changes, addl~/onal cement may be required to a~ur~ stren~tl~ ~ld pu~p'~13zli~y at additional cost to the contractor. 6.

To ensure minimum air loss when pumpins, maintain a continuous flow of concrete through the entire length of pipe and do not subjec~ concrete to free fall. 7. The term "pumpable concrete" refers to concrete which is capable o~ being transported throush an appar'atus which forces concrete to the placing posxtion through a pipeline or hose as long as the recommendations indicated above are followed. The term "pumpable concrete" does not relate to concrete proportioncd in a particular m~%er or cu~L~ini~ a specific type of product.
