Get PriceGenerally 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 …
Get PriceAnother factor in mix design is the consitency (slump or flow test) of the concrete. A higher consistency will allow the concrete to move more readily within the pump and pipe-line. However, an excessively high slump can cause the concrete to segregate resulting in plugs of coarse dry material in the pump or pipe-line, the paste beign squeezed out.
