What pumping mechanism is used in a concrete pumping Related Information

Use of Water Reducers, Retarders, and Superplasticizer

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.

How a Concrete Pump Works| Concrete Construction Magazine

Aug 01, 1994 · How a Concrete Pump Works. The pumping operation starts with the discharge of the concrete, usually from a ready mix truck, into a hopper large enough to hold a small supply of fresh concrete. In the hopper an agitator keeps the fresh concrete flowing smoothly into the pumping cylinders. Concrete piston pumps operate on the same principle as a
