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
