· The ideal concrete mix for pumping typically contains airentraining agents, a little extra sand (compared with a standard concrete mix), often some fly ash, and a wellgraded aggregate blend. To make the concrete easier to pump and place as it comes out of the hose, many batch plants also add waterreducing admixtures — known as superplasticizers — to their concrete.

Higher cement content mixes are generally easier to pump. The difference between a typical 3000 PSI mix and a typical 4000 PSI mix is that there is approximately 100 pounds more of cementious material and approximately 85 pounds less sand in the 4000 pound mix. Cement is the sliding agent in concrete; while sand is abrasive

These are the actual concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete that I use to pour concrete floors, patios, pool decks and more. I'll show you the actual concrete batch plant ticket with the cement, sand, and aggregate break downs for the yards we used.
Mix Design and Pumped Concrete. By KAUSHAL KISHORE Materials Engineer, Roorkee. A simple method of concrete mix design for pumpable concrete based on an estimated weight of the concrete per unit volume is described in the paper. The tables and figures presented are worked out by the author from a wide range of Indian materials.
· As concrete mixes become more complex in order to address everincreasing needs for strength and durability and to meet environmental sustainability standards, concrete pumpers often face challenges when it comes to moving concrete through pump lines with the efficiency demanded by accelerated construction schedules.

· The Mix Design 283 Thus a high consistency (high slump) concrete has a low plastic viscosity whereas a low consistency (low slump) concrete has a higher viscosity. The viscosity, however, gives no information about the ability of the concrete to withstand pressure gradients and, at this point in time, a laboratory type test which measures this property under variable pressures would be valuable.
