COMMENTS: l)ale: 6/8/2(105 Mix Name: 8272 GENERA~ NO =' ~ Pumping Notes: l. 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 gout 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 fail. 7. The term "pumpable concrete" refers to concrete which is capable of being transported through an apparatus which forces concrete to the placing position fl~rough a pipeline or hose as long as the recommendations indicated above are followed. The t~rm pumpable concrete" does not relate to concrete proportioned in a pa~cular manner or contaimng a specific type of product.
