A pumping aid is a lubricant that improves the ease with which a given mix can be pumped through a line. This means lower pump pressures, reduced pressure on the mortar phase of the concrete, less chance of segregation and a reduction in internal friction.
WRA has been used primarily in hot weather concrete placing, pumping, and tremie. Careful concrete placement is required, as the initial setting time of concrete will take place an hour earlier. It is also shown that the use of WRA will give a higher initial concrete compressive strength (up to 28 days) by 10% compared to the control mixture.
29/1/2020 · Ruttura says the ideal is to "have at least 270 pounds of water per cubic yard, although we can pump it with down to about 230 pounds with a well-blended aggregate.". Putzmeister A wide array of factors can impact concrete pumpability such as the dimension, shape, gradation, and volume of aggregates and fibers.
