  • PCC : Pumping of concrete

    The work of the TC can generate a report and recommendations similar to the ACI-304 and ACI-211.9 documents, intended to inform the industry on how pumping pressure can be predicted or altered (304) or on how to modify the mix design to make concrete pumpable (211.9).

  • Best Mix for Pumped Concrete | JLC Online

    Mar 01, 2010 · Generally speaking, the maximum slump for a pumped mix is about 6 inches. The ideal concrete mix for pumping typically contains air-entraining agents, a little extra sand (compared with a standard concrete mix), often some fly ash, and a well-graded aggregate blend. To make the concrete easier to pump and place as it comes out of the hose, many

  • Principle of mix design for pumpable concrete

    Sep 23, 2020 · A pumpable concrete, like conventional concrete mixes, requires good quality control, i.e. properly graded uniform aggregates, materials uniformly and consistently batched and mixed thoroughly. Depending on the equipment, pumping rates may vary from 8 to 130 m 3 of concrete per hour. Effective pumping range varies from 90 to 300 meters
